aFe MACH Force-Xp 409 Stainless Steel Exhaust Muffler, 4-Inch Center Inlet/Outlet

The aFe Universal fit Aluminized or 409 Stainless Steel Performance Muffler is designed to provide a deep, throaty, powerful sound on acceleration but maintain a smooth sound at idle. This muffler is constructed of either Aluminized steel or brushed finished 409 stainless steel and uses a straight through perforated core with heat resistant packing to reduce backpressure and maximize exhaust flow. You will see increased performance and improved throttle response over the factory exhaust. MACH Force-Xp 409 Stainless Steel Muffler 4 IN ID Center/Center x 8 IN Dia x 30 IN L

• Stainless Steel Construction
• 2 Year Limited Warranty
• Improved Exhaust Note
• Increased flow

The aFe MACH Force-Xp performance muffler is designed for universal exhaust applications requiring improved flow, responsive performance, and a deeper exhaust note. Constructed from durable 409 stainless steel with a brushed finish, this muffler is engineered to withstand the heat and demands of automotive exhaust systems while providing a clean, professional appearance.

Inside, the straight-through perforated core promotes efficient exhaust flow and helps reduce backpressure. Heat-resistant packing helps deliver a deep, throaty sound during acceleration while maintaining a smoother tone at idle. Compared with many factory mufflers, the aFe MACH Force-Xp design can support improved throttle response and a more engaging exhaust character when properly matched to the vehicle’s exhaust system.

This universal-fit aFe muffler features a 4-inch inside-diameter center inlet and center outlet with an 8-inch outside diameter and a 30-inch overall length. Installation may require custom fabrication, exhaust tubing, clamps, or welding because vehicle-specific mounting hardware is not included. The aFe part number 49-91002 is backed by a 2-year limited warranty. This product is not CARB approved and may not be legal for use on pollution-controlled vehicles in all areas; verify local emissions requirements before installation.
