So back to OEM midsection but with the mufflers. Hopefully I can maintain 50% of the sound because it's nice. Someone talk me into keeping my set up because I was planning on a Dinan remap.
Evolve showed in their exhaust testing that 200CPI cats make a small difference in terms of power. I can tell you that the smell is not really bad at all either once they are warmed up. It will be stinky during cold start.
