The MagnaFlow 6in. Round Straight-Through Performance Exhaust Muffler 12649 brings our world-famous exhaust sound and dyno-proven performance to your ride in a weight-optimized 6x6x18in. package with a premium satin finish. The straight-through free-flowing design of this round-bodied muffler's reversible, universal 3/3in. diameter inlet/outlet layout enables versatile installation options to match the spacing requirements of your vehicle. Due to the cutting and welding involved, professional installation is highly recommended.

Amelia A. ★★★★★

The weight is noticeably less than my old setup—easier to handle during installation. I also appreciate the consistent dyno-proven gains; my truck feels snappier on the highway.

David D. ★★★★★

The sound is deep and aggressive without being too loud for daily driving, and the weight savings over my old muffler were immediately noticeable. Welds look clean and the 18-inch body fit perfectly in the stock location. Took about an hour to swap out, and the difference in throttle response is rea

Daniel ★★★★★

Bolted this onto my truck last weekend, and the 6x6x18in. round body cleared my bed crossmember with zero hassle. The straight-through design gives it that deep, aggressive tone without the drone I was worried about. Weight feels noticeably lighter than my old chambered muffler too.
