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

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!!!

Super happy with this. Sounds awesome. Price is better than anywhere. My neighbors might not be as happy. But it's so much quieter than my old exhaust. Has that cool rumble and no drone on the hwy. My person can actually talk to me when I'm driving........(as if I'm listening lol.)

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.

Sounds great on my truck. Really let's the engine breathe. Very well made and it has increased the torque and throttle response in my my old pickup. Only drawback is the drone in the cab however alot of that may be just my setup as I just put a turndown pipe 18 inches off the back of the muffler.
