Testimonials

- I bought the exhaust in early december and have had zero regrets, John sent it earlier than expected, it was packed well and has a very nice finish. Only exhaust i would consider over this is the Ruf but than again it is 3.5 time the price. - Christian in Memphis

- I bought my 2001 911 Turbo in February of 2007. Since that time I've changed exhausts four times. I went from a modified Stock Turbo exhaust that rattled, buzzed and droned, to a Fabspeed exhaust that was much lighter (More than 30#), but also buzzed the heat shields and droned between 2-3K. It was so much so that we just didn't drive the car much. I switched back to another modified stock system, which also did the same as the previous two systems. I was thinking about buying a new system, and looking at all the popular systems from AWE, PSI, Fabspeed and Europipe. What was simply killing me was the price range of $2800-5200. Talk about the Porsche tax!!! Then Speedtech came along with their new system. John posted on Rennlist.com and 6speedonline.com about how his system didn't drone. I wasn't buying, because I'd been burned by others. Well, after much back and forth with Q&A, I finally bought the system and put it on the car... No drone. NONE. The car has a musclecar/exotic sound, and the system is of the highest quality with a mirror finish. To add function to form, it's a true 70mm system from the catalyst flange to the ring for the ehxaust tips, which are also 70MM and look stock. The system also removed a lot of weight of the car, at least as much as the Fabspeed, if not more. The price of the system was the real kicker... I'd been eyeing a set of Victor Equipment wheels that I was thinking about buying, but the exhaust was first on the list. Well, the Speed Technologies system saved me enough money over the other systems to buy the wheels and the exhaust for the same price range of the other systems... So I feel like I got the wheels for free!! This system is on a K16/K24 hybrid Car that's making over 500Wheel HP, and not long after installing the system I attended a road course event and a drag strip private rental day at MIR in Maryland. At the drag strip I was able to run deep into the 11s at over 124mph, spinning the length of the track after pulling the front wheels off the ground at the launch. The system helps the car make more power and run better in my opinion. Thanks John for such a great and cost effective exhaust system!!!

- John,

I just wanted to drop you a few lines to share my impressions of your exhaust. As you may remember, I have a 2001 996 Twin Turbo. My car has been UMW flashed, K&N filter, Forge Diverters and now your SpeedTech exhaust system.

I have to say that prior to owning my 996TT, I have owned 2 Dodge Vipers and after changing their exhaust systems several times, I never really got the desired sound... therefore, I was VERY hesitant to change my 996TT exhaust due to the high cost and fear of a getting a loud & raspy system.

Thank you for the time spent settling my nerves. I have to say that for me, I think that your system is perfect for my 996TT, especially at WOT. The stock exhaust was too quiet, however, now, my car sounds like a Porsche 996TT should sound... not too loud at WOT and not too quiet around town...

Thanks again,
Carl (Austin TX) -TIPTRONIC TRANSMISSION


- I am very happy with my new Speed Tech exhaust from AST. I made my decision after reading several posts on Rennlist and 6 SpeedOnline. The Speed Tech product seemed to offer the most value for the money. John and his team delivered unbelievable support before, during, and after the sale. They were very patient and friendly.
The exhaust sounds great. The stock exhaust is much too quiet. I am very pleased with the final product.
Thanks for great product, terrific price and outstanding service!

- exhaust is insane! I love it! AND it does add some serious power. Fitment, finish, sound are all top notch! I have had a PSI loud, and RUF and this by far is the best. My brother will be in contact with you to buy one as well. Thanks for the smooth transaction.

Just a quick note to say many thanks for shipping the exhaust which arrived very quickly and safely. Local motor sport centre fitted the item and they, like myself, were very impressed with the quality and sound of the unit. They said it was the best one they had fitted! I am getting used to the sound which has a real rumble at low rpm, so makes the car sound much more aggressive. It is plenty loud enough especially as fitted to a cabriolet so I have not forgotten that you do the quiet inserts, but for now I am quite happy to make my presence heard as I clock up the miles........

Thanks again

Hey Chad,

I've had the cat back on my 03 WRX for a week now. It's mated up to a grimmspeed catless downpipe. Fitment is awesome! i didn't use the kartboy hangers yet, so it sits a little high but I will be throwing them in once the weather warms up a little. As for the sound all i can say is WOW! It sounds really nice when it idles, but when you open it up it's ungodly...lol I love it! I find there is very little drone at highway speeds which is great in my book. No complaints from the lady either. We're going to install the TBE on my friends STI over the holidays here, so i will send you a quick note on how that goes. On a side note: Delivery was very fast and well packaged. Thank you Chad! Have a Merry Christmas and a Happy new year!

speedtech crossflow! worth it!

i just wanna tell the board that i just installed a crossflow x cellerator loud version today and it was awesome. the sound is exotic like and i felt the difference in terms of torque or maybe its just me. But the car is more responsive and definitely gets notice with the exotic sound. Even my mechanic was impressed with it. He said it sounds SICK. I
definitely recommend this exhaust for the price, sound, performance, and very good customer service. Keep it up John.
P.S - I have no affiliation with speedtechexhausts.com, just expressing my opinion and appreciation.

I have the quiet version of this exhaust and am VERY pleased with it...Drone is minimal and I'd compare it to the EP2 quiet that I've sampled in other members cars...

997TT X-cellerator X-flow experience

John has designed a great exhaust system in the x-flow accelerator. I have had the 2.5 quiet on my car for 1-2k miles now and I think it offers just the right balance of aggressive sound without drone. It provides a unique, exotic type of sound for the 997TT and is not overly quiet despite the label. At WOT, it is much louder. I have paired it with a BMC filter and Evo recric valves, and the sound is just where I like it for street. For track use, I'm planning to run it with the muffler bypass set up for a little more volume.



Speedtech is the way to go I just installed the 2.5 cross-flow, great product very nice quality and great sound.

After trying some exhaust systems ... I ended up with Speedtech X flow 3 inch system ... Sound is awesome and i wont change it...

John,

First,thank you so much for taking my word for it that i didn’t receive the decat pipes and sending them over straight away.

Secondly...you should market the exhaust without cats – i wish i had a HD recorder to provide a sound clip as the 2.5” exhaust benefits hugely from the removal of even the 100 cell cats. I can’t believe how much crisper the note is...there’s a distinct edge now, with the traditional Porsche howl up top, very muted with the cats in place before.

The best part of all this is that THERE IS NO DRONE.

Hi John:

The package arrived yesterday. I was looking at a crazy work week and couldn't wait. I had my indy shop in Reno install it today. The mechanic who has 30 years experience in building P-car race cars was very complimentary. He said the quality and ease of installation was easily on par with much more expensive systems. He also commented on how different (in a great way) the sound was. I completely agree.

I just got back from a good run and all I can say is I love the sound. I am so glad I went with the
loud version. The band of drone is very small and easy to avoid. In fact, the drone really doesn't bother me at all. At idle it is downright quiet. At WOT it is a glorious sound. I was really impressed with the improved throttle response the most though. The car just feels entirely different. I was pleasantly surprised at the improvement a simple mod like this makes.

I'm running the 2.5 quiet as well, with CATS on it's very quiet,
little to no drone, I actually prefer the no CATS setup, makes it a tad bit more aggressive.
Great exhaust, passes the wife and kid test, price is reasonable, give Speedtech a call

I've run five different exhausts on my car in the 4.5 years I've had it... I FINALLY found what I feel is the perfect SUB $3000 exhaust system... Contact John at Speedtech and talk to him about his Xcellerator QUIET. I was in your shoes long ago, with the Fabspeed... And three other systems... Don't expect I'll be swapping out exhausts anymore... The wife is even happy with it... And when I "commute" in it, it's a 150 RT to my customer's location. This car now is actually fun as a daily driver without the headaches and with the ability to talk on the cellphone or listen to the stereo on LOW volume.

Had this system for well over a year now, with 5K miles on it... This one is the "right" one... for me, anyway!

My 2.5 quiet x-cellerator from speedtech experience

I haved owned several exhausts for my turbo, five now in total and thankfully my last. I LOVE LOVE LOVE my 2.5 quiet x-cellerator exhaust I got from John at speedtech.
Personally I had the crazy loud droney exhausts, the boring stock (but drone free) exhaust note as well as some models in between. But nothing sounds as sweet as this cross flow. Its hard to explain its just right, not too loud as to annoy my neighbors but a monster when "I" want it to be.
