So Ive been out of the country for the past year and gathered up some money. Since my cat has been starting to go (@ 76K Miles atm) and my exhaust was too loud with stock cat w/o a muffler, especially the awful drone while cruising at 75-85 mph; I decided to go out and search for a solution. Needless to say I settled for RP Supercat w/ turbo xs exhaust. The sound is beautiful. I was afraid I'd lose the nice deep tone with stock cat and tail pipes, but no, this thing is a gentle grumble at idle and screams at low pitches @ WOT. I can once again enjoy talking on my bluetooth on the highway and not get a headache from a drone that i used to get around 75-85 mph. This is huge for me since i often drive down from NC to FL and it takes a good 11-13 hours depending where in FL I'm going. I've never tracked the 8 yet so I have no insight on the perfomance gain side, but as far as sound goes, I couldnt be more satisfied.

Super thankful to Rotary Performance, very experienced and kind. Same goes for TurboXS. Both manufacture a beautiful product.

 

Congrats on your solution.

Now post em sound clips!
