I like the look of the factory exhaust on my Cayenne Turbo..But i want a deeper, louder sound. What's the best way to acheive this without removing the factory exhaust? I recall reading about straight pipes (Removing the secondary Cats). Who makes them and where can i pick these pipes up?

Also, how does it sound?

Thanks!

 

Sounds EXCELLENT with 2nd cats removed. I would also swap the primaries with high flow units. It's simple plus you keep the OE mufflers. Fabspeed makes the pipes: http://fabspeed.com/cayenne.html

 

Ditto on the Fabspeed pipes. I think Suncoast has them. The only thing is finding a shop that is willing to remove the secondary cats. Most will tell you that legally they can't...
You can also try to do it yourself since all the pipes are bolted on rather than welded.

 

The secondary cat's delete does free up some sound, not much but better than stock

 

+1 get a set of pipes
you won't be disappointed
if you want louder you can go from there with different mufflers etc.

 

Thanks, Guys! I just spoke to Fabryce at GMG.
I'm going to drop off my Cayenne and have the pipes installed. If i want louder i'll have him install a TUBI exhaust.

 

secondary cat bypass pipes... and/or the cargraphic exhaust. Not sure what year your pepper is but we've got a video up in terms of the sound. You do get a bit more power too

 

Alex can you provide the video link?

 

Can you still pass emissions with the secondary cats removed?

EDIT: Looks like it does. I know what I'm getting! I'd like a more aggressive sound but feel an entire exhaust system would be louder than what I'm looking for.

 

I pulled the secondary cats on my Murcie and it passed emmissions with flying colors..So i'm sure the Cayenne will have no problem passing.

 

Secondary cats removed here and no problems with emissions.

 

Nice! How's the sound? I remember when I removed the cats from my old vehicle it got much throatier.

 

wow if you watch the video on the fabspeed site of the ctt taking off its pretty exciting.

 

WHOA! After watching that video I ordered the bypass and EVOMS intake. Exciting!

Anyone wanna buy my 2 week old BMC panel filters?
