I love the way it looks and sounds, and you cant beat true duals with a h-pipe for about 300 bucks
-Would you change anything?
I would like some high flow cats and headers, but that is later down the road, and it gave me quite a performance gain in the butt-o-meter.

 

Ok I might as well put mine in here since I just had mine done.
