Unlock the true power of your 2007.5–2010 Chevrolet Silverado & GMC Sierra 2500/3500 HD Duramax LMM 6.6L with this 5-inch Downpipe-Back DPF Delete Exhaust System, built from premium T409 stainless steel for durability and performance. This high-flow race exhaust begins at the downpipe, eliminating the Diesel Particulate Filter (DPF) and Catalytic Converter, allowing for unrestricted exhaust flow. With no bungs for maximum efficiency, this system lowers exhaust gas temperatures (EGTs), improves engine breathing, and delivers noticeable gains in horsepower, torque, and throttle response. Engineered with OE-style hangers and all necessary clamps, hangers, and fasteners, this kit ensures a clean installation. Most installs can be completed in about an hour with basic tools, and it may require slight trimming on shorter wheelbase models. ✅ Key Benefits: Increased horsepower & torque Improved throttle response & engine efficiency Reduced EGTs for better reliability Aggressive race exhaust tone (optional muffler available for quieter setup) Built from T409 stainless for long-lasting strength ✅ Fitment: 2007.5–2010 Chevy Silverado 2500/3500 HD Duramax LMM 6.6L 2007.5–2010 GMC Sierra 2500/3500 HD Duramax LMM 6.6L Category: Ram Cummins Tags: 2007.5 Duramax LMM 5 inch exhaust, 2008 Chevy Silverado 2500HD DPF delete, 2009 GMC Sierra 3500HD Duramax exhaust delete, 2010 Duramax LMM 6.6L performance exhaust, 2500HD Duramax race exhaust system, 3500HD Duramax DPF delete exhaust, 6.6 Duramax turbo back delete, Chevy Silverado Duramax downpipe back exhaust, GMC Sierra Duramax stainless exhaust kit, off-road Duramax performance exhaust Brand: FDP-TU
