Just converted my 07 Sport to a cat back system. If you are like me and like a nice Tone out the back during acceleration, but want peace & quite at cruise/deceleration,try this muffler. The Borla one in and 2 out, part No.(40670) worked great for me. The Muffler Shop Owner had it on his half ton pickup for about six weeks, but wanted more snap-crackle & pop and removed it, My Bargain, try it you might like it?
