Built with everyday performance and reliability in mind, this universal-fit muffler is designed to handle diesel and gas truck applications without unnecessary bulk or complication. This muffler features a 4-inch inlet and outlet, making it an easy match for most aftermarket or custom exhaust systems using that standard size. The body measures 24 inches with an overall length of 30 inches, so it’s a direct swap for systems that use the same footprint, like MBRP’s earlier M229 model or other similar mufflers on the market. Aluminized Steel Construction It’s made from aluminized steel, which gives you solid corrosion resistance while keeping the price more accessible than stainless alternatives. It holds up well in typical driving conditions and is a great fit for daily-driven trucks, weekend haulers, or work rigs that need dependable performance without going overboard. In terms of sound and flow, this muffler is designed to provide a nice balance. It tones down the harshness of raw exhaust while still allowing your engine to breathe. You won’t get the drone or restriction that comes from some factory mufflers, but you’ll still maintain a clean, crisp tone that works well on both stock and lightly modified setups.
