So I'm thinking of adding a couple of power and exhaust sound mods to my '07 911 C2S.

I do have Porsche Sport Exhaust, but I was thinking of adding the Fabspeed muffler bypass, as well as the Fabspeed Maxflo CAI.

Are these worth it for the price?

If you want the sound than go for it...Don't expect any head turning hp numbers...I did the headers, cat bypass and cat back exhaust system along with a CAI and my numbers on the dyno were a little below stock hp...check my thread in this forum...

Good luck...

 

I had PSE on my 2008 997S and the sound is great as is. Want to do something positive for power and intake sound think about an IDP plenum, and CAI.
