## Description

Flowmaster 74151 3.5 In(C)/Out(C), 5X8X18, Flow Fx Muffler

Review: I'm excited for cold starts. A very mellow rumble - I'm running this on a 2012 6.2 denali. It sounds amazing. Just enough to where you can hear it. But not too much where the sound is obnoxious. Keep the resonator, delete the third cat, and you have a very tasteful sound. Even none car people have complimented it. The box looks like it survive world war II. I dont know what it went through in shipping. the muffler itself had a couple small dents but I didn't mind. It was still usable

### ⭐⭐⭐⭐ Loud with headers...
*by J***E on September 21, 2023*

Great quality.. But with long tube headers on my 6.0 gas Silverado.. it's loooouddd... Bad drone.. sounds good. But not a good choice for daily or tow rig.
