Great muffler, Great price

Bout this for my '14 150 5.0. Someone I know in my family has this on their ram and it sounded great so I decided to get one for my truck. Deleted my resonator and replaced this for the muffler and I am very happy. It was obnoxiously loud for a week and since then it has broken in and quieted up a little. Also has made my truck gain quite a bit in fuel economy even in the cold weather.

Pipes Violator muffler review

Reviewed By Tyler A (TECUMSEH, MI) Reviewed for a 2007 Chevy Silverado —1/11/2017 4:18 AM

All I can say is wow... the sound from this muffler is incredible, when you have a V8. Great flow and really made my truck sound mean. Definitely has a good amount of drone around 1200 rpms but throughout the rest of the rpm range it sounds good... If you want to get noticed and be heard from blocks away, this is the muffler for you.
