Great muffler. It definitely quieted down my 2nd gen Cummins significantly, but it is still loud. The size is a perfect fit for a 5.00" exhaust and it's very easy to install. It look roughly 10 minutes to cut out the old section and weld on the muffler. I can have a conversation pulling our trailer or just cruising again. Quick and easy!

'22 ford with 5" exhaust + 8" muffler. Got rid of the sustained drone that would kick in around 1600 rpm with the straight pipe. Still sounds good and can hear the turbo more clearly with some of the background noise gone.

When you purchase mufflers this inexpensive, you do not have high expectations. These sound excellent, went on easily, and did exactly what they were supposed to do which was quiet down a car with open headers. Excellent buy and I would recommend these.

I really like this muffler. I installed it on my '15 Cummins, which had been straight-piped for several years. I was tired of the cab noise, so I installed this muffler. The truck still has a nice rumble on the outside, but the cab is much quieter, which is nice for hauling trailers long distances.

This seemed well made. Its just an open muffler. But it added a nice tone to the old F-150. I put a new Walker down pipe in when i Got rid of the EGR. It had a seized air pump and a bad EGR valve. I added this to make up the difference in removing the ALSO 2 cracked stock EFI exhaust manifolds. Which was pricey to replace those with OEM exhaust Manifolds. As they flow about as good as a header set up. I then connected it in line. From exhaust manifolds to the Walker Down pipe to this muffler/ resonator. Then tothe stock muffler to the stock tail pipe assembly. So short story long .. I uded this to teplace the front half of my exhaust.... Works great... Sounds better. Not so much like the tractor sound I hear on modified old 4.9s.
