MBRP Armor Plus 4" Filter-Back Single-Side Exhaust for 2007-2010 Chevy/GMC 2500/3500 HD (Duramax LMM) T409 Stainless

Fits 2007-2010 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD models equipped with the 6.6L Duramax LMM engine.

This MBRP Armor Plus Series filter-back exhaust system is engineered to improve the performance and efficiency of your Duramax LMM. By replacing the restrictive factory tailpipe section from the Diesel Particulate Filter (DPF) back with 4-inch mandrel-bent T409 stainless steel tubing, this system significantly reduces backpressure and helps lower Exhaust Gas Temperatures (EGTs). The mandrel-bending process ensures the tubing maintains its full diameter through every curve, preventing the rippling and flow restriction common in crush-bent pipes.

Built for long-term reliability in various climates, the Armor Plus series uses T409 stainless steel, a material that offers superior corrosion resistance compared to aluminized steel while remaining a cost-effective choice for truck owners. This specific configuration features a single-side exit and a "no muffler" design, as the factory DPF provides the necessary sound suppression while the MBRP piping delivers a rich, mellow exhaust note without drone.
