The MagnaFlow 4in. Round Straight-Through Performance Exhaust Muffler 10424 brings our world-famous exhaust sound and dyno-proven performance to your ride in a weight-optimized 4x4x18in. package with a premium satin finish. The straight-through free-flowing design of this round-bodied muffler's reversible, universal 2/2in. 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, 10424 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.

Lily ★★★★★

Installed this on my Mustang GT last weekend, and the 4-inch round straight-through design really opens up the exhaust note without adding a ton of weight. The sound is deep and aggressive at WOT, but it's surprisingly tame cruising on the highway. Definitely delivers that dyno-proven performance I

Henry ★★★★★

Swapped this 4x18 straight-through onto my truck and the sound completely changed, deep and throaty without droning on the highway. The round body fit the space under there way easier than the stock can.

James ★★★★☆

The 4-inch round case fit snugly into the stock location on my S10, and the straight-through design gives it a deep tone without being obnoxious inside the cab. Just wish the included clamps were stainless steel so they'd match the muffler's finish better.
