Review on Silent Performance: Unleash the Power with MBRP M1004A Universal Quiet Tone Muffler by John Lewis

Revainrating 5 out of 5

I replaced the ATC muffler which was cracked and rattling.

Replaced the mufflers that were cracking and rattling in my Duramax. This muffler appears to be well built and runs much quieter than the old one. While driving I only hear engine noise, not the exhaust, from the outside of the truck the exhaust sounds about the same as any other Duramax.

Pros
  • Few competitors
Cons
  • Annoyed
