Review on 🔊 MagnaFlow Oval Center/Offset Performance Muffler Exhaust 5x8 Straight-Through Satin Finish - Model 12229 by Richie Jacobson

Muffler was excellent and arrived brand new undamaged. The muffler gives the engine a nice deep idle that's noticeably louder than stock. Not as loud as the Flowmaster when idling, but still noticeable. the engine turns fine. However, don't buy it if you have a GM Chevy or GMC V8 truck because the drone is absolutely AMAZING. You'd better buy a Flowmaster 40 or 50 because they make less noise. This muffler was excellent on my f 150 with a 4.6 v8 engine (which made minimal hum when installed).
