Love it
Did oem muffler delete for my 2013 xterra and paired this muffler with vibrant resonator ultraquite, idling and cruising the noise is super low, and on full gas it gives this deep gravel noise

Nice welds, seems to be real stainless. Installed as a dual in single out on my FJ Cruiser. Has a unique sound compared to a typical chambered muffler.

Awesome exhaust for the price! It went straight from the delivery guys hand onto my 04' ram 1500 5.7. Sounds great!

2014 gmc 5.3l. I left the forward resonator and flex pipe, then went up to 3” and into the muffler. Then came out before the axle. Sounds great! Not super loud. Just a nice low growl. Will add pics when the exhaust tip comes in. Definitely recommend!!!

Put this muffler on a 2016 Ram 1500 5.7 HEMI with the single rear side exhaust. Most Rams have the factory dual pipes, and there wasn't a lot of options in the aftermarket for a direct fit for the single exhaust. This one fits perfectly, offset lines up, just had to add a length of pipe to make up the distance from he stock muffler. Sound is good. Cold starts are a good bit louder, but once warmed up, idle is very quiet. The deep rumble from this makes it idle almost quieter than stock. No drone at cruising speeds. The factory system drones at changeover from MDS, and this muffler kind of amplifies that, more so when getting back on throttle from coasting. Normal driving and accelerating has a good tone, sounds like a V8 should, and not like a vacuum cleaner like stock. Just a good rumble, nothing obnoxious. When you let it eat, it'll bark for sure, but again, a deep rumble, not a raspy, obnoxious noise.
