Exhaust question

[JWendt]

I am wondering if there is a something other than a cat back system to replace the stock muffler and resonator? Or would i have to do a cat back?

Get yourself a MBRP muffler. Your 06 exhaust system is already 4" so why change the whole thing. The muffler has hangers welded on to fit the stock setup. Nice rumble when you get into the throttle but sounds stock going down the road at speed. No drone at all and mine lowered the EGT's around 75 degrees.

well i should reword it do that make a a straight pipe for the resonator like they do for the muffler?
