about a year ago i had dynomax race bullets welded in. now i want to have a full catback, as i'm looking to get an h or x pipe soon. however, i want to keep my mufflers and have 2.5" piping with 3" tips. are there any companies that sell some sort of tailpipes that i could attach to my mufflers or am i better off going to my local muffler shop, if so how much am i looking at spending? also what would sound best with my mufflers, an x or h-pipe. i'm most likely going to get an off road one and just swap it with the stock everytime smog rolls along.
