Review on MagnaFlow Exhaust Products 12772 Muffler by Shane Hartford

Revainrating 4 out of 5

Very quiet muffler in exhaust and emissions

Everything came on time and was in brand new condition. I only installed it because the state changed the law requiring my Cummins direct-pipe diesel to have a muffler AND a turbo. I bought the DC model thinking it wouldn't do much, but the insertion loss is pretty high. Any sounds I like are muted, which pleases the condition. Although I miss making my truck sound like a dump truck.

Pros
  • Excellent overall performance
Cons
  • Frequency
