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 .

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!

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.

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.

No drone no loud exhaust sound
It's been real good. No more loud noise. No drone noise either. Installed an F-250 6.0 diesel that was straight piped. All you hear now is the turbo. You don't hear the engine exhaust rumble and growl. Would highly recommend. The tone of the exhaust you cannot hear from the driver seat or passenger seat. But you do hear the turbo..

Buy one definitely worth the money keep neighbors happy!
The media could not be loaded. Used on a 6.6 Duramax I have a 10 blade 64 mm turbo so I attached a video what it sounds like at idle with the veins closed and then the veins open. Very impressed for the size. The whistle of the 10 blade is still heard when accelerating, no drone at all.
