Good quality for a great price
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.

As advertised, works well
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 not fit over 4" pipe.
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.

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

Tamed my 6.0 Powerstroke
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.
