This muffler has a very good sound. I am using the 2 1/2 inch tubing and duel exhaust and the mufflers sound great. They are a little loudr then the regular 40 series.

FlowMaster Super 40 series
Pros: Great Sound, Acts as a Muffler Skid, Tough as HELL, Improved MPG
Cons: instead of baffles in the muffler, would like to see straight flow for added gains, slight drone when at a constant high speed
Recommended? Yes

Comments: I actually installed the Flowmaster Super 44 Off Road series muffler. It is awesome. It is basically a skid plate and a muffler in one. Great deep rumble, nice and loud when you romp on the throttle. It does have a little drone, but nothing bad at all. I got about 1-2 mpg gains from this muffler, but lost it as soon as I lifted my KJ.
