Perfectly Loud. Not crazy loud but it will wake up neighbors when you rev it.

The best upgrade for the money on any truck I believe it, sounds amazing on my 2015 Toyota Tundra Limited. Loud and Mean but no rasp one bit it even crackles and pops in manual shift mode, no complaints I think it’s the best mod to solve your research on finding the best sound that isn’t annoyingly loud and isn’t quite one bit when you get on it.

-Replaced big 4 or 5 chamber muffler from a after market catback on a 2012 tundra. Even with 5.7l going from oem single exhaust to a dual exhaust I could feel a drop in low rpm torque. With this smaller muffler I think the lost torque is back.-Definitely sounds better than oem and other after market exhaust.-Only down side is drone picked up-i guess it may bother me if I drove 80mph on interstate towing but most it sees is 65 ...maybe 70 and not for extended periods of time.

Installed this muffler on my 2003 SIlvarado 6.0L V8, dual 3" pipes reduced to 2.5" coming into the muffler with dual 2.5" coming out the back with 4" tips. The muffler sounds great, cold starts sound exelent, not to much sound volume wise but when you get on it that changes quickly. If need be driving gently can make the exhause quiet but if you want noise that is very easy. Overall great sound, easy install, good price.

If you like a really loud deep rumble then I would recommend this. I have a 2012 toyota tundra crewmax and this is my 2nd one. By far my favorite exhaust. 10 series!

Love the sound of this Muffler. I put it on my 05 Ram with shorty headers and a cold air intake, throttle body spacer and a Hypertech programmer .it sounds great when you're on the highway just cruising I can hear the intake whistle more than I can the exhaust .so for you people thinking it may be to loud .its not with the set up I have .but when you get on it man it opens up and sound mean. You get a lot of head turns in town when you give it a bite.
