  1. Holy Moly!! 5 Star Review

    Posted by on 9th Aug 2017

    I recently purchased and installed these cat bypass pipes on an '04 Cayenne Turbo. I wanted improved performance but did not want a loud exhaust under normal driving conditions and that's exactly what I got.

    Performance was rated at +27 hp and the difference is very noticeable. The vehicle runs much more efficiently. My Cayenne has a little more growl under normal driving conditions and when I mash the gas, the engine sings.

    I'm noticing MUCH less turbo lag and as the turbos spool up, they pull stronger than ever. I can't believe how much this simple enhancement allows me to speed through the gears.

    I'll go as far as to say that these pipes are the second best performance enhancement for these vehicles, only short of a computer tune.


  2. What they claim is what they deliver! 5 Star Review

    Installed these cat-bypass pipes in my '06 Cayenne Turbo with the intention of a mean growl and rumble with improved acceleration and that is EXACTLY what I got. The sound these pipes make on idle and WOT is just down right incredible!

    The acceleration and throttle response has increased drastically as well with improved boost response with no delay whatsoever.

    Keep up the great work, Fabspeed Motorsport!
