Amazing sound on a V8
This is the 2nd Dynomax muffler I've bought. Extremely happy with the sound, got and performance of their products. Magnaflow like sound(imo) for a bargain price. Will continue to use their products.

Sturdy and quiet
Actually way quieter then I was expecting. I didn't go with a glasspack because I wanted to use my existing exhaust piping, and for that I needed an offset muffler. Super pleased with it on my 1989 Chevy G20 with a 350 in it. When you do give it gas it has a really deep pur to it.

Not my taste
I purchased a pair of these Ultraflows (3") to replace my 2 chambered race mufflers on my 60's era muscle car. After driving around for a few days I had them removed and replaced with another pair of chambered mufflers. These ultraflows did reduce backpressure but lacked that classic muscle car cackle.
