cat by-pass pipe
what do you think of the cat by-pass pipe [fabspeed] think it will sound good? how about will it set off cell lights etc. i'm looking for better sound fron exhaust on my turbo without being to loud.

Did you watch the video's on the fabspeed site with the cayenne S and TT???They are a good indication of the sound. They will not affect emmision sensors since they are connected to the primary cat, not the secondary cat which is removed for the bypasses. FYI, the secondary cats are bolt on bolt off, so they can always be put back in rather easily if there are inspection or warranty issues at hand...

could not get the video's up on my computer maybe because its a "mac" would like to know with air filters and cat by-pass where and if the extra power would be in the power band

I have an S, so no advice on the TT. Bypasses not available yet and I only use the BMC air filter at this point. It gave me a significant improvement in throttle response, but may be less noticeable in the turbo due to spooling issues...where there will always be a brief lag..I know that the sound improves greatly if you do the complete package, bypasses and sport mufflers...Try to find a PC somewhere to view the video's...They really do give you a good sense of what to expect...

I went with Leistung resonated bypass pipes on my '09 GTS. I had Fabspeed pipes on my previous '06 S, but they were very raspy with hard throttle and at higher rpms. The resonated pipes sound simply magnificent. My Cayenne has a sound much more like an AMG Mercedes, now. This is good.
