[quote=HUM GOOD]I ran a catback Borla set up......also borla short headers. The sounds is very quiet on the highway and screams when you step into it. I went to a friends shop and install it on his lift. Time was about 2.3 hours. Very simple. The performance wasn't much...just sounds badass. After K&N cold intake, Granatelli MAF sensor, & Granatelli power tune - now it doesnt only sound mean, it is mean.
Thanks for the info looks like a nice exhaust system. Is there a lot of drone in the cabin? or is it pretty mellow at crusing? Also is the Granitelli tune similar to superchips or hypertech? I was looking at the Zoomers exhaust because it's a true dual system with an X-pipe. I heard them at my dealer and I really liked the sound. Has anybody got this set-up?

I may pull the trigger this weekend it really looks like a well built system really different than anything else out there.
