FWIW, Speedtech are one of the few left these days using the quality header design with true merge collector and one piece primaries all the way to the flange.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Our 3-piece exhaust configuration is designed to mount to factory mounting points.
Purchase all three components at once or slowly build your 996, one component at a time and enjoy each stage.
Headers: High-flow design. Polished SS.
X-Flow mid-Pipe: 200 cell high-flow mid-pipe or optional catless. Approximate HP gain of 10HP over factory mid-pipes. This helps refine the exhaust note to pure symphony over traditional dual pipe designs.
Traditional OEM Style mid-Pipe: 200 cell high-flow mid-pipe or optional catless. Approximate HP gain of 10HP over factory mid-pipes.
Cat-back: Designed to provide a more aggressive note vs the OEM system. There is no cabin drone with this cat-back. Choose from stanard sport muffler or our "Sound Valve" model that allows you to switch from our standard sport tone to a race sound with the push of a key fob button.
For best performance and a more aggressive sound we recommend upgrading the mid-pipes as well.
Polished mirror finish, re-use OEM tips for factory look.
Please contact us for pricing or any questions.
John, this looks like a different setup than the X-Flow 2.5/3.0. Is this a new exhaust option for the 996TT or a phase out? Do you have YouTube videos for sound, installation, and comparisons?
KrazyK, We only have reports from customers...There is not a lot of HP gain on a normally aspirated car, unlike the turbo cars. On a 996NA - it is mostly for improved sound, better throttle response and weight reduction...all with a slight bump in HP. The sum of all these factors dramatically enhances the driving experience.
Thanks for the recent orders - we appreciate the Rennlist community support!
And remember, we offer special discount pricing to all Rennlist Members...
I have the Speed Tech X-Pipe and 200 cell high flow cats and they have been on my car for almost two years without any issues. I could not be happier with the sound and the performance
FWIW, Speedtech are one of the few left these days using the quality header design with true merge collector and one piece primaries all the way to the flange.
More companies back in the day had the same design but due to costs and profits, they've gone to using the cheaper/crude collectors, 2 piece primaries, and stepped primary coupler at the flange.
These are the ones to get these days if you are thinking of a header.
BTW, I'm in no way affiliated with them but just think they offer quality products and great service.
