Muffler is a Flowmaster. Its not too noticeable on the street but when I took it out on the dirt at Palomar Divide it had a definite rumble to it when I was putting around in low range.

The Duratracs are pretty cheap comparative to BFG MT's or The Wrangler MTR's. I see tire rack has them for 153 ea for 33's. Not sure how durable they are, but the neither the BFG's or the MTR's Ive owned have impressed me with sidewall durability as I punched holes in both. Only with the cheap General Grabbers I had was I never able to poke a hole in the sidewall..Go figure. The traed compound on these seem a bit flexible, but that might be due to the siping. I bet they would be killer on the slickrock in Moab.
