Review on 🚗 Enhanced Performance with Flowmaster 43041 40 Series Muffler by Jason Cox

I bought this to replace my rusty stock muffler on my V-10 powered F-250. The build quality is excellent. Well welded with standard pipe. I didn't put any pipes on the exhaust side because I think that quieted the muffler too much. Even a small twist made it noticeably quieter, but that wasn't what I was aiming for, so it went on the fly.
