    shorter magnaflow, I had 22" and hated it, now a 14" round is a lot better.

    I have a smaller manga flow I think it's 14" round. It's too loud for me, but I will trade you for yours and pay shipping on both.

    You got a video of what it sounds like? I might be interested

    Oh, and before we do this, I have no idea how many miles the muffler has.. I bought it with 130k miles and the truck now has 167k.. when I cut the muffler to put on the new pipe, there were flakes coming out of the muffler..

    Sounds like an even trade since I also have no idea what miles are on mine either. I bought mine used as well.

    I don't have a clip, because I never installed it. Bangbangskeetskeet had the same muffler for a while and he liked it until he went crammed and then he thought it was too loud for a DD.

    This is Travis's truck with a pretty good sized cam and LT's. http://i460.photobucket.com/albums/q...1/b3a57792.mp4

    I have a magnaflow catback on my truck. Installed it when I still had the V6 and it actually sounded pretty good under 3K RPM, got pretty raspy when I really got on it though. It sounds really badass now with the LS6!
