Anyone running the borla XR-1 bullet muffler? I just bought one from lmp performance and I'm curious how to make it work with my cme. My current muffler is 1 in, 2 out. Also how do they sound? When I bought the muffler I was under the impression that it was the same design as my current one. Its a straight through muffler so I'm sure it will be loud. I like loud so im good with that:devil:
