DEVELOPMENT AND TESTING: We wanted to get as aggressive as possible while minimizing drone – greater volume with a greater amount of pops and burbles on deceleration. Support for high power was another consideration – necessitating 3″ tubing. We experimented with adding a mixing chamber into our X-pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system. Helmholtz resonators were engineered to target and reduce droning in the 2000-300 RPM range. Quad race resonators make a discernible difference in reducing drone while encouraging a more refined exhaust note.
SOUND: You’ll finally be able to hear the exhaust and turbos sing in full song! Expect a very aggressive sport cars sound at full throttle. The 996 Turbo platform is prone to droning in the 2-3k RPM range with freer flowing exhausts. Our Helmholtz resonators and quad resonators cut down on droning, but volume in the cabin is certainly pronounced – this is a system for this who like it aggressive. If a refined cabin experience is more important than a CUP car inspired tone, our catted Sport exhaust is a more suitable option.
CONSTRUCTION: Each system made from mandrel bent T304L 3″ .065″ wall stainless steel tubing, straight through race resonators with a full metal packing design for maximum durability, and laser cut brackets for perfect fitment.
BOLT ON AND GO: Each exhaust is tested in a fixture to guarantee fitment and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.

My experience with Soul Exhaust on my 996 TT was great. Had the install done a few weeks ago. Went with X-pipe system. Completely transformed the car in the best way. Cold start is ferocious, perhaps a bit much. Once warm it settles into a great sound. Perfect out on the road, in cabin and totally motorsport at wide open throttle. Love the look from the rear, no scrapping issues on a stock ride height car. Everyone at SOUL was fantastic to deal with. Highly recommend this system !!

SOUL competition exhaust on the 996tt provides the ideal exhaust note for the turbo.
The competition exhaust truly gives this vehicle its SOUL and is quiet enough in the low 1-2.5rpm range but when you hit the gas brings the vehicle to life while reducing turbo lag and giving the vehicle the extra hp.
After research of many exhaust I can happily say this is the ideal exhaust for the 996 turbo and look forward to new innovations created by the SOUL performance team as they are now my go to company for any exhaust modifications.
