6.7L power-stroke is quiet in the cab!!
First off, I NEVER write reviews, However I couldn’t be happier with this muffler. And it has been super quiet since install. Just what i wanted!!! With a deleted 6.7L powerstroke there was plenty of room to install and i put this one with almost half under the cab and half under the bed. It seemed too quiet in the cab. For the money, i think it was worth every dime!

It's greaaaat
Cheap, effective and seems to be durable. Been on the truck over a month or so now and it doesn't have any noticable corrosion. It really quieted down the exhaust, that being said it still makes a little bit of noise. Install was super easy with some stainless clamps I purchased separately. Over all I would highly recommend for anybody looking to quiet down there truck .

Worth the money.
Great compromise between a stock muffler and a straight pipe. It kept the deep tone of my 7.3 Diesel but now I don't need to worry about waking the dead and my neighbors. I'd guess it has lowered the full throttle volume 25-35 decibels. Visual build quality and welds are as good as stuff I've had for 2-3x the price, can't say anything for durability yet. Side note, most of my turbo whistle and noise is gone now, so keep that in mind if you're addicted to listening to those Wu-Tang War Whistles.

Installed on a 4th gen Cummins. Took the drone noise out of the cab and quiet's done the exhaust/turbo noise. Can still hear the turbo spool up just not as obnoxious.

so good so far
I was thinking for long time about replacing my stock muffler on my 2004 dodge ram 2500 cummins and I did and sounds good so far I Little bit louder for me maybe in the future I will replace it with some more quiet moffler
