After driving around with no mufflers for six months I'm would like to go in the other direction. Nice and QUIET!! Now I would like to have a single 3" exhaust out of the muffler. Are there any with dual 2.5" inlets or should I go with a single 3" in single 3" out and have the pipes collect before or at the muffler? Please dont foret...QUIET!!! I would like to be able to listen to the radio and have a conversation without yelling.
