Mattyrae is infamous around these parts
Sounds great, and love the fin. I can't stand the stock 996 turbo fin / rear wing, one of the reasons I bought a GT2.

Even on the 997's, the GT2 wing should be a factory option. After the 993, the Porsche Turbo wings went down hill.

This is my personal favorite option, the sound in the uper rpm range is unreal in person...you can kind of hear it in this video.

Happy Thanksgiving everyone!

John,

100 cell cats with muffler bypass is louder due to the lack of a sound reducing device (muffler). However, the quality of sound is nowhere near our X-Flow system and I feel the catless system outperforms the catted muffler bypass option.

I have not comparatively dynoed those two options, but I would say based on driving that the catless 3.0 would offer the greater performance. The turbos spool much quicker when catless and the car rockets when it hits that turbo sweet spot. I could feel the difference doing a direct swap from cat to catless same day. The car feels really light on it's feet and free of restriction with the catless race exhaust and drives really, really nicely. It flys with this system installed!

:-) I wonder where I got that idea for the music fill.


Sounds great, and love the fin.
Thanks, Matty - I'm a fan of the aerokit on the 996TT, too.
