So right now I have a rather large Hahn muffler. Its pretty large and doesn't sound too bad. However, its a little to quiet for my liking and I really want an exhaust that fills out the space in the bumper. Are there any nice sounding cans available?

So you want something like the Ark Performance N-II exhaust.

Only problem is that it's a 2.5'' vs your current 3'' piping.
