I finally got out in the shop last night and put my borla catback on the mach. Great sounding. Nice change from the old tried & true Flowmaster stuff. Fit great, sounds great :thumbsup: I would definately put this as the best sounding set-up I have owned. Not to mention, I dont know if it was due to it being a little cooler last night or if it was the exhaust but my car finally woke up. 3500rpm on it was running much better.
