Thanks for the answers. I think understand what you are saying; you replaced 2 in. of peforated pipe in the resonator with 2 in. of your exhaust pipe.
Did your exhaust shop make it easy to put back the old muffler? Is there anything you suggest when we ask or request the exhaust shop do when we do the muffler delete.
What do you think about running the one-into-two y splitter earlier and having two long tailpipes come out of the bumper?
