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.

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

Do you have the dyno charts that show HP and torque gained at what RPM's for each mod on a N/A 3.6? @10HP is not very specific.

John D II

This is a 996 non-turbo exhaust...

John D II

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.

OK thank you.
