Hi Everyone,

We had a new GTS in this week for a secondary cat bypass pipe install. The sound is amazing! We didn't dyno this particular car, but expect a +12 HP increase. Please check out the video below and let me know if you have any questions. Please PM me for discounted forum price. Thanks!

are these the same pipe as the S?

 

Yes... Same size and flanges as the S.

Jeff

 

Sounds great. Could you post pics of the part, perhaps also comparison with the standard one and pricing please?

 

Here is what they look like. Sorry, I didn't take a picture of the OEM cats. I sent you a PM with the price. Vendors aren't allowed to post prices in this forum. Thanks!

Here is my 13' GTS with Fabspeed the Cat Bypass driving by. I love the sound, really changes the feel of the 958 while staying relatively tame with the 'sport' button off. Thanks Fabspeed!

 

Here is a picture of the pipes and the installation

 

Sweet! Thanks for the vid and pics.

hi jeff

actually I'm interesting to get these pipes. but I'm worrying about the warranty. our local dealer not allow any modification.

so, is it need wilding job or not? it will keep any mark or signs if I install back the original parts?

thanks and regard

 

There is no cutting or welding needed to install these pipes. You can go back to stock at any time and the dealer will not be able to tell that you had modified it. Please let me know if you have any questions. Thanks!

dont i get a check engine if i installed the secondary catbypass? thank you jeff !

 

Is it available for the V6 Cayenne ?

 

I don't believe so b/c it only removes the secondary cats, not the primary.

 

we installed my fabspeed bypass pipes last night and the quality was awesome ( i just shot a quick pic as we were working..wasnt finished). the sport exhaust tone is nuts now! i really like it and really make the exhaust even more of a jekyl/hyde type system depending on your mood. throttle response also seems a touch punchier. i do have some smell from the pipes, but my understanding is that it will go away as more miles go through the pipes.

 

So have got some more seat time and also had the wife in the car today. When really getting on it in sport, im getting quite a bit of straight pipe backfire, or 'burbling' sound...she's not so sure about that part anyone else had a similar experience?
