Bolt On Filter Back Exhausts

Upgrade your 2007.5–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of premium LMM Duramax filter-back exhaust systems. The 6.6L LMM is equipped from the factory with a restrictive diesel particulate filter (DPF) and a crimped tailpipe that traps heat and severely muffles your engine's natural exhaust note. A filter-back (or DPF-back) exhaust system bolts directly to the rear of your factory emissions equipment, allowing you to significantly increase exhaust flow, lower your exhaust gas temperatures (EGTs), and achieve a deeper, more aggressive tone without the need for custom tuning or deleting your emissions components. These systems are an easy, bolt-on upgrade perfect for daily driving and heavy towing, designed to keep your truck completely emissions-compliant. Available in massive 4-inch and 5-inch diameters, you can choose from budget-friendly aluminized steel for dry climates, or premium T304 stainless steel for ultimate corrosion resistance. We proudly supply industry-leading filter-back exhausts from trusted brands like MBRP, PPE, and aFe Power.
