The MagnaFlow 6in. Round Straight-Through Performance Exhaust Muffler 12640 brings our world-famous exhaust sound and dyno-proven performance to your ride in a weight-optimized 6x6x27in. package with a premium satin finish. The straight-through free-flowing design of this round-bodied muffler's reversible, universal 2.5/2.5in. 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. Internally, 12640 utilizes a perforated stainless steel core wrapped in stainless steel mesh and acoustic fiber fill to achieve a powerful, resonant tone. This muffler is made of durable, corrosion resistant stainless steel and produced using cutting-edge CNC precision robotic manufacturing techniques, all backed by MagnaFlow's limited lifetime construction warranty.

Amelia K. ★★★★★

The straight-through design gave my truck that deep, throaty growl I was after, and the weight savings over the stock muffler are noticeable. Installation was straightforward with no surprises.

Evelyn J. ★★★★★

The 6x27-inch body fit perfectly in my stock exhaust tunnel without any modifications needed. It gives my V8 a deep, aggressive tone at WOT without being obnoxious on the highway—exactly what I was after.

Benjamin ★★★★★

Installed this on my truck and the straight-through design gave it a deep, aggressive rumble without being obnoxious on the highway. The 27-inch length fit perfectly in the stock location, and it’s noticeably lighter than the old muffler.
