Upower 4" Inlet Diesel Exhaust Muffler 7" x 24" Body 30" Whole Length XS2772 - Straight Through Stainless Steel Welded On Resonator Muffler

Great quality piece for the price. Sound and tone is exactly what I was looking for. Highly recommend

This works depressingly well for the price. I put depressingly because I miss the deep loud sound of my 22 L5P. With that being said, it works great! No more drone from my 4" exhaust when pulling our trailers or cruising on the highway. You can still hear the exhaust and the turbo whistle, but it controls the drone and the whistle. The metal is thick enough to weld it on perfectly and the muffler looks good in place.

Sounds good and the price was right.

I love it. Sounds great

Seems quality : came with a clear coat of some kind on it. On my 6.7 deleted truck it's not doing much for low frequencies. Truck is quiet but boomey. Not much drone but not eliminated either. Good for the price but don't expect miracles here : it's just a straight through muffler.

I have a 6.0 Powerstroke Excursion that came with a straight 4-inch exhaust. At over 40 years of age, the sound was just too much for me. Luckily, I was able to remove an old section and slip this one on—installation was incredibly easy. The difference is night and day! Now the engine makes all the noise, with just a muffled exhaust and faint turbo whistle. Exactly what I was looking for. Like my vehicle a bit more now.

Appears to be good quality, arrived well packaged and undamaged. Installed easy and quieted my 6.4 diesel up almost too much! Very happy and would buy again.

Worked good to take the drone out of the straight pipe

Purchased this for a 9,000KM Road trip in my 5.9 Cummins 2003 RAM 3500 with a 4" MBRP turbo-back exhaust and muffler. The truck was LOUD. Added inline as a resonator as far forward as I could in the exhaust, and it dropped the volume out the tailpipe by at least 80% while also removing most of the in-cab drone. Muffler is holding up fine after that 9,000KMs. Great unit.

I do not write reviews much this product for the price works awesome for my deleted 6.7 cummins dodge ram 2500 2015. Sounds just like factory and not loud and won't upset my nabours anymore. Very happy.

I bought myself a full 4" performance exhaust system on Amazon expecting it to be a bit louder than stock. Turns out it was obnoxiously loud and something had to be done. I saw this muffler and the great reviews so I thought I would give it a try. Wow, it makes a huge difference. Much quieter but still nice and throaty. No restrictions either so it wont rob you of any power. Gotta say that I just love it. It wont disappoint.

appears to be decent quality, sound is nice, might not be loud enough if you're a billy big rigger wannabe (although you will not drive your neighbours crazy). stainless is questionable, magnet will not stick anywhere.

Works perfect and takes the obnoxious noise away and makes it sound good.
