killerFatty Posted November 25, 2008 Share Posted November 25, 2008 I believe it's 2" in and out, but i could be mistaken. I have wanted to put a pair of cherry bomb mufflers on my 93, but i havn't had the time. Let us know of your results. Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted November 25, 2008 Share Posted November 25, 2008 I've got 2.25" piping, Magnaflow X-pipe, 2 Thrush Magnum resonators, and 2 straight through mufflers. Sounds awesome. I don't think you'll get TOO MUCH sound out of JUST a couple replacement pre-mufflers. If that's what you're going for. My entire system said and done was probably about $400 ;) Quote Link to comment Share on other sites More sharing options...
