All I can say is WOW!!! I went to FABSPEED today to pick up the BMC filters and I ended up also doing the CAT BYPASS done. I must say the sound and performance is great. I also must say that everyone at FABSPEED was excelent. Now I just need to figuire out which performance software to go with...FABSPEED, GIAC or UPSOLUTE...If you have any opinions please post...Thanks...

 

and what type of cayenne do you have ...........?????

 

Cool.....

bypass and bmc are awesome..

I would recommend GIAC since I've had it on my previous CTT and very happy with the result.. I tried softronic on my 997 and it was great also..
I havent seen many softronic Cayenne's maybe you should try it

 

Oh sorry, 2005 Cayenne S

 

GIAC only

 

how much did the bmc filter and cat bypass cost? im really thinking about gettin it done.

 

Coste me $910.00 everything installed..

 

Is there a specific reason why GIAC only??

 

how much percentage of performance increase have you noticed?

 

I recomend Protomotive software! Had mine done at Protosport in NJ and love the way it drives. Should give you well over 500+hp with the filters and Bypass as well.... I smoked a modded Subi STI in my CTT. I didn't think I would have a chance ...

 

You should post a vid on the sound! I have bmc filters but havent done the bypass pipes yet and would like to hear it on an S, most videos are on turbos

 

GIAC and Protomotive would be the first choices.

 

Wow! 500+ is a pretty big jump for a Cayenne S. Don't you think?

 

Yeah he probably misunderstood the vehicle type. There is no way to jump Cayenne S to 500+hp. You can jump a <08 CTT though
