I used this on my diesel tuck just to mellow the rasp out a little bit. It did that and gave it a deeper tone over just being straight piped, but didn't sacrifice the overall sound. If you plan on welding this in take the extra time to clean the ends since there is an oily residue on the metal.

Good quality muffler for the money. I only wish I had bought a slightly longer one.

Came fast and easy to install I put it on my Ford F800 diesel, was straight piped and this quieted it down a fair amount. Sounds great.

Does the job. I'd give it more stars if it were a slip fit over the pipe like 99% of the other resonators & mufflers on the market. This one must be butt welded in or have your pipe expanded.

Small but works really good in tight spot, best if you use 2 mufflers probably not enough by itself

Used this on my 2004 F350 Powerstroke and it made a huge difference in the cab. I have been running a 4" straight pipe for years, but I'm getting to that age where I don't care for all the noise. Still have great sound outside, but now I can hear myself think when towing a heavy load. Very happy, highly recommend.

Put a pair on my small block chevy to reduce noise enough to meet sound requirements for racing. Got rid of the crackle and rasp i had with dynomax mini bullets. Good quality, would be nice if the outlet was expanded to slip fit.
