Can you send me a quote so i can order a set of the stainless polished chambers for my KH500. UK delivery. 

I've had an early set of yours on my H2 750 for over 10 years and they've been faultless.

Thx. Ken. 

Hi David,
I have purchased a set of your stainless chambers for my gt 380 trough Murray West.
They arrived today and I would just like to let you know how happy I am with them.
The workmanship is absoluetly first class, so good. They fitted perfectly and sounded even better than expected .I have been around bikes for a long time, 59 years old and started at 15 and have not, until now had such a performance gain form just putting a set of pipes on.
 
Once again, congrats on your ability the provide such a quality product and keep us two stroke lovers alive.
 
Regards
Terry Booth (AUSTRALIA)


Almost finished with my 400. Fired it up for the first time the other night and it sounds wonderful!. Your pipes really add to the look, and superb quality, fit, and finish. And a bargain in my book! Thanks for the quick turn around and a top quality product!

Hello David,  "I LOVE THE PIPES"  The looks, the sound, the performance are super.  Install was non eventful and please see the pictures.  Now my bike is better than ever and tip-top.  Thank you very much for these beautifully crafted H2 pipes.

Hi David, I did get your email about sending you some pictures for your website.  I will once spring comes and I can get good pics.  The pipes are awesome!  Love them.  As you said more midrange...true.  Makes the bike really work for me on the roads I ride.
Thanks,
Aron

Heya just thought I'd send you some pictures of my X7. Took it for the first ride today after 6 mouths of work and was the first ride with the Higgs pipes on. I was overwhelmed by the difference they made. The sound is stunning and response is sharper, below 5k rpm is so smooth and above it just screams. The engine has been balanced and with bore and port and so on but without the pipes it was falling flat. Thanks for taking the time to make pipes for the older two smokes they look sound and preform so well.


Dear David

 

My new pipes arrived today for the Kawasaki 400S3.  I especially requested the low-level setup as it reminds me of the old H1R racers. The entire system was an immediate and perfect fit and the whole job took less than 30 minutes.  No re-jetting was required (standard air box) and all I needed to do was turn the air screws in from 1.75 turns out to 1.0. The bike starts first kick, has a livelier feel to it and looks fantastic. Did I mention the noise?  It really is the soundtrack to my youth; a lovely crackle without being offensively loud.  I am absolutely delighted and would recommend your product without hesitation. If anyone has a specific question they are welcome to contact me via Twitter  @classicrider 

 

Kind regards

Paul Miles

Hullo David,
 
I’ve had this KH500(in H1 spec) for 4 years and it’s never run properly.
I have looked at/pulled apart carbs, checked porting etc etc.Ignition timing etc etc.
I had started to suspect the std rechromed(repaired) exh system as a possible problem.They were a bit rough cosmetically.
 
Anyway I fitted the Higgspeed  pipes and “tweaked” the side stand and can tell you that the 3-4 thousand stumble is completely gone!
I now discovered that the clutch slips when hard at it.
Very pleased, dead chuffed.
Great dealing with you.
A happy customer!
 
Cheers Ian.

Hi David, just a quick note to say how pleased I am with the expansion chambers 
I've just purchased for my 1975 H1. They fitted perfectly, look fantastic and 
sound eargasmic! I am very impressed with the quality, finish and value for 
money. I would certainly recommend these pipes to anyone wanting to revive "the 
sound of the seventies". A big thank you to you and your guys for a great 
product and service, they do exactly what they say on the tin. Good luck and 
keep up the good work.
        Regards Glyn.
            (happy customer)

David- Don here, I apologize for just now getting back to you on the pipes, I dug a little deeper in the restoration, knowing I had your cans coming. What a treat, They fit like a glove. I am so impressed, so is everyone I show them to. Tins are being painted soon, the lime green, @ white. If there's a place, site, I can go to and talk up you, the company, the pipes, the time frame, everything you say and some, I could not be more pleased. Let me know. Thanks, Don

David,

Please see attached photos of my recently restored 1975 Suzuki GT550 Triple 2-Stroke. I only just got the opportunity to “make smoke” this past weekend, after nearly 13-months of rubbing and lots of TLC every where this piece needed it. And it needed it everywhere, believe me..!!
I have several more high-quality photos of this finished-hardware. Hardware, with an odometer showing just over 5,120 miles. Of course, this thing was less than pretty when I obtained it over a year ago………but it had potential, and no serious damage, wear or problems beyond mainly the cosmetic, maintenance items and general good ole’ fashioned elbow grease wouldn’t take care of.

I’d be happy to forward more detailed photos if you desire some examples of fresh Japanese hardware of significant rarity and quality. Significant rarity and quality due in large part…………because this piece is fitted with the absolute highest-quality, uniquely engineered, superbly crafted, well-designed, well-executed expansion chamber exhaust system available anywhere on planet earth. My Higgspeed chamber system delivers a unique sound at all revs that is unequaled by any other expansion chamber system. The quality, the uniqueness, the utter beauty of the music this system makes at the turn of the key – cannot be adequately described or compared. It’s simply not possible. One has to experience Higgspeed quality and uniqueness first-hand, up-close and personal to fully appreciate the symphony. I’ve heard dozens of uTube videos, all attempting to capture and duplicate the resonance for all to hear. However without a single example or exception, none can capture the two-stroke-tones of the Higgspeed system. Simply put, the video’s, sound tracks all fall well short of duplicating the vastly superior quality of a “being there experience”. Believe me, I know, and I am offering this testimony as one very, very happy customer who offers his whole-hearted, sincere recommendation and indeed endorsement for the Higgspeed exhaust system.

More photos to come David. Some close-ups of your art work, your invention if you will, are to follow and to serve as proof of another very happy customer that speaks from practical experience. Even if your exhaust system were twice the price, I would rush to make the purchase. I say that with two (2) qualifiers; (1) assuming I had the money at-hand, I’d make an immediate purchase, and/or would save as a priority until I had the money needed for the purchase and, (2) I can make this statement with all due sincerity and intent – after witnessing first-hand the superior quality of product and tonal quality of this system. If there were some way to convey the rarity, the fantastic sound quality, well, doing so would undoubtedly lead to more sales.

That said David………….one more point that is of some considerable importance; the power increase, the felt horsepower gain, the raw but even, smooth and unfettered torque and felt-power gains, are measurable and of considerable improvement over the stock, heavy exhaust system of the Suzuki GT550 and I am sure the GT380 and GT750 class bikes as well I’m sure. Simply put David, I immediately noticed, in conjunction with a musical-magic, a noticeable performance gain which can be directly attributed to the installation to your expansion chamber system. We are talking serious performance gains here……………..”THE HIGGSPEED CHHAMBER SYSTEM WHEN INSTALLED - YEILDS SERIOUS HORSEPOWER IMPROVEMENTS OVER THE STOCK EXHAUST FROM THE MANUFACTURE”.

With all that said, I’m sure glad I chose to speak to you before I ran off the deep end and chose the brand-X exhaust, I hope my testimony will help others who are on the fence, and unsure of the best system to select for their money. I’d say to these folks……..”save up a few more coins, wait a while if you have to. But by all means, give HIGGSPEED a good, thorough look and serious consideration prior to selecting any expansion chamber system for their 2-stroke motorcycle. It will be the best decision you’ll have made in the performance/appearance-improvement phase of your motorcycle ownership experience”.

PS. If you decide to use any of this for testimony for your site, I hereby grant permission to edit, delete, add, or correct to suit your needs as long as the general spirit of the testimony remains intact as per my satisfaction with your products, attention to quality, and superior customer service.

PATRICK FROM CALIFORNIA...........UN-EDITED!! THANK YOU PATRICK

David,

Received my pipes yesterday... They are excellent. I couldn't have asked for better. You are truly a craftsman. Again, thank you. I'll send you a picture of them on the bike when I get it all back together.

Cheers.

Jeff from USA ....GT500 suzuki january 2012

David,

I've got to tell you, that I simply cannot believe how FAST you got these museum-quality chambers from your site to my front door..!!!

I actually heard the door bell ring like no more than 24 hours after I sent my email requesting details of the delivery of this product. I mean, it was so quick that I was wondering if you had those pipes pre-positioned here in the States, just waiting for me to place the final order. Heck David, I've placed orders for goods 5-states away and have waited longer for their eventual arrival than I have in your case, where your pipes had to cross a huge pond to arrive at some custom's warehouse only to be delayed for yet more drawn out days upon days awaiting some bureaucrat's approval. Bottom line David, it's not your fantastic customer-service, your superb communications with your customer base, your obvious dedication to over-the-top world-class quality............no, it's all that and more, like your ability to transcend time and space and get your product over her without haste and at near lightening speed - Higgspeed to be more specific..!!!

Now, in the interest of your time, I'll not tie up any more of your time, but to say this; I was home when your product arrived, a matter of consequence, not by chance or plan, all the same when the package arrived at my front door, I was delighted, excited and after inspection, overwhelmed at the sheer quality and attention to tolerance and detail that escapes the vast majority of your competitors'. Simply put, your product is superior in all aspects to that of your competition here and abroad. I know this to be true, as I've seen all the others product, and can personally attest to the obvious dedication to your craft and avocation.

Patrick from USA ( i did have them in stock already to be fair!!)

Hi David,

The chambers arrived safely, they are sensational. I had no trouble fitting them to the bike, however i did have to buy some shorter bolts as the standard header bolts are a bit to long for the flanges on your pipes, but that was not an issue.

They sound great, and look great. Do you have any jetting recommendations for your chambers? As a starting point?

Thanks again for your work. I will certainly reccommend Higgspeed to anyone.

Bryce.

BRYCE FROM AUSTRALIA... GT750

The Higgspeed expansion chambers are made entirely from stainless steel, so no rust and no need to rechrome, just polish and ride!!
Before you all pipe up (pardon the pun ) 'isnt stainless heavy??' they are laser cut from 0.9 mm sheet and are 1/3 lighter than standard. This means that all 3 including the baffles weigh the same as one standard pipe. The baffles are removable (stainless grubscrew underneath) and repackable. The front pipes are cnc mandrel bent, which means no wrinkles or creases. The front flanges bolt to the head, then the pipes just push on, with 2 springs to retain them. They are individually custom built on a bike to ensure a perfect fit. Lead time is about 4-6 weeks per set.
Performance wise, they make a big improvement over standard, but i cannot quote figures as no 2 bikes are the same,well they are 30 years old!! As with all 2 strokes each bike must be jetted to suit, but i can give you ball park settings to start from. These are a limited production run made from a genuine enthusiasm for the bikes



"Thought you would like to see pictures of your pipes fitted to my s3
I'm very pleased with them Fantastic quality really easy to fit in fact
i will probably remove them for cleaning as it only takes 5 minutes to
remove both sides they also sound orgasmic, the first time i started the bike i nearly wet my self!!!!!
And they are so light compared to the standard exhausts.
I will be ordering another set for my kh250 very soon
Thanks again for a great product and fantastic service
Regards Danny "

David,
Just got my pipes today! Absolutely beautiful! Thank you so much, now I have to get the rest of the bike looking that good,LOL! Couldn't be happier! Thanks Again!, Eric

ERIC FROM USA

Hi David ........ just writing to let you know that the chambers are fabulous, I'm very pleased with them aesthetically, and with the finish and performance. The H2B is now very strong, it goes like 'stink' and the chambers sound just perfect IMHO. Also, the fit was just absolutely perfect to the mm. I would happily recommend your pipes to anyone if they wanted an opinion.

BTW, just in case you may be interested, I ended up using K&N pod air filters, 110 mains, a 42.5 pilot and centre clip on the needles ....... running 95 RON petrol with Motul 710 2 stroke oil and a fresh Wossner 2nd OS top end.

many kind regards

'Ow do David,
Well, on opening the box it was obvious they look good, after fitting and swinging on the kick start it was undeniable they sound good and after a brief half hour ride it's indisputable they feeeeeeeeeel good!!. A quick rush hour spin in between the rain showers and it was amazing the difference these pipes have made. Considering I've geared it down to avoid the Micron flat spot I used sixth gear more times in that half hour than in the past six months!. I think a return to standard gearing is in order, my left foot couldn't keep up . Just a little fluffle at 4000 revs like the carbs are scratching their heads making their minds up what to do and then it's off like a roman candle!. Heh!!. No flatspot, no nowt. Just zings right round the dial. . The noise needs no description, just lots of appreciative nods of respect from dewey eyed middle aged blokes in Tranny vans and such. . ( which is me when I'm not on bike!). Keep up the good work my good man.

Hello Dave,
I would like to apologize for not getting back to you sooner to thank you for the pipes.
Finally rebuilt motor and went for a test thrash today. I am absolutely thrilled with your pipes. Not only do they sound brilliant, the workmanship and finish are first-class.
Highly recommended!!!
Thanks again, Mick

"Hallo David!!!

The door bell rang in yesterday and when i locked behind the door a postman had a big parcel for me.I ran into the garage and opening it.
WOW I could`t hold my self from test mount the pipes.
The pipes was better then expected. The best,so nice.

Best regards Sven-G Foss "

Greetings,
The pipes I ordered from you arrived last Monday (8 weeks like you said).
the box was a bit beat up, so I opened it quickly to find one killer set of
pipes
for my 1974 Kawasaki S-3. Today I actually has some spare time, so I
installed the pipes... They were very easy to install and look great.

I'll enclose 2 pictures. #1 is the before and #2 is the finished product.

They look and sound great. Thanks for helping me with this bike...

Dave:
  I received your pipes Monday and I wanted to tell you that they look great, I am a Manager of a welding and fabrication shop and your workmanship is excellent.
Thanks again.
 

Dave,
Just been out for my first ride in anger since you fettled the carbs and timing and fitted the pipes. It's running great and sounds awesome; quality work on the pipes and the running and not wanting any recompense for a couple of hours working on the bike is old school service. Thanks!!
You were also right about it oiling the plugs after a few miles, five miles to be exact but fitted 2 new ones and she's flying.
I'll recommend your work to anyone who asks.
Thanks,
George.

Hello David,

After a year long restoration, my h1e is done.
The pipes are of outstanding quality, and sound. Everywhere I go, people comment on the beauty of your pipes. Those who are are of them, ( I'm in Canada. ) plead with me to start the bike so they may hear their sweet (angry) song! Excellent on the road in regards to drive ability as well!

You'll soon hear from me again, as my 72 H2 project is about to begin!

Cheers

Hi David,got the pipes,all I can say is WOW,they are fantastic.Fitted them to my bike on Friday,they look and sound great.
Well worth waiting 8 weeks for.
Thanks very much.

Steve Coates

Hi David,
Just had to drop you a line to say how pleased i am with your exhausts.
I fitted them towards the end of last year so never really had a chance to ride the bike a lot, now the bike has been fully run in and I am letting the engine perform the pipes have come into their own.
Previous to your pipes I had all speeds fitted which I felt were a bit fluffy with the way the engine performed.
Your pipes however make the engine feel crisp and it has a definitive power band as soon as it rises over 3,000 rpm, and the sound pure heaven.
I am running all stock carburation and filters with no dramas as advised by you at the time I purchased them.
Just one observation the down pipes has started to show a very very slight discolouring (a yellowing) I assume this is down to the heat? maybe you could advise me on that.
 
Thanks once again for a quality product,
 
Regards Nigel

Hi David. My pipes arrived today. What an absolute work of art. They will draw a crowd at the next classic bike rally. Exhaust makers here are still using corrugated iron!

Cheers mate.

Could not be any happier with the pipes. Beautiful work, fit perfect. The sound is fantastic. 
All power issues are gone. 
Let me know if you would like some pics.
Do you have any of the older, silver and black Higgspeed stickers for the pipe? Would only need to purchase one ( for outter r/s pipe) Also, how do I get my hands on a t-shirt with that cool logo on it!
Thanks again for the help and the great product, 
Tim

Hello David,
