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 on my 07 ram (has cats, no resonators) and it sounds very very good . Minimal drone at cruise or at highway speeds but just a touch loud for my liking . I have used many different brands of mufflers, but this one put on a Hemi almost gives it a slight lope/chop at idle or cold start that is pretty impressive . Would recommend if you don't mind it being on the louder side, but what do you expect for a straight through muffler. definitely not as loud as a glass pack.
