Stuffed one on today. The fit was perfect, sounds much better than the stock pipe with a Dynomax. Power-wise, it actually pulls better than my previous set-up. I noticed more torque on the hills, and it just sounds great with the throttle down. I was sceptical about the flow design of the muffler itself, but it works.
I definitely recommend the Flowmaster cat-back, worked great, looks great with the 3 1/2" stainless tip.
Two thumbs up!
