Looking for real world feedback on the secondary Cat bypass..

I have a '13 GTS and the only year (that I know of) GTS that doesnt have a separate "sport exhaust" button.
That translates to an annoying dilemma. Put the GTS on "sport" to hear sporty exhaust, but put up with jerky shifts, transmission holding high RPM in gears and PASM in sport mode by default (although this can be addressed by pushing "normal" on PASM)

It seems the secondary Cat bypass would produce a more sporty exhaust note even in normal mode and I wouldnt need to press multiple buttons and change PASM just for some sporty exhaust note.

Any feed back is appreciated..

On the 957 you can plug the exhaust valves and have the sport sound all of the time regardless of drive mode.

desmotesta,

I installed the Fabspeed secondary catbypass pipes on my 2012 Cayenne S as the stock exhaust is SOOOOO quiet. I've got PSE on my 2010 911 C4S Cab and I LOVE the additional growl above 4,000 RPM, so I wanted to get a better sound on my PiG. I posted a thread with a before & after video clip to show the difference. It's a really nice enhancement versus stock, but unlike PSE you can't toggle it on/off so the neighbors get the full-throated version on the winter mornings that I drive the Cayenne S and leave the 997.2 Cab at home

Here's the thread in case you're looking for a before & after video, at least on an S: https://rennlist.com/forums/porsche-...cayenne-s.html

Based on the description of your goals, it definitely sounds like our SCBP would meet your goals. PM heading your way.

All about that full throated version! Mine is a little bit more intense on the Cayman...so I tried to be nice one morning and put socks up the tailpipes on start up but that failed miserably, oh well lol. Thanks for posting up your review!
