Replace the Duramax resonator box with our 6061 Billet Aluminum Resonator Delete. Our Delete securely fits over the intake fitting where the stock resonator box mounts. This will give you a secure Plug utilizing Predators Double O-Ring design. This also gives you substantial peace of mind knowing that the stock resonator, which is prone to cracking and letting in dirt into your engine, is no longer a threat to the longevity of your Duramax. It also fits all Predator Duramax Diesel conversions on Hummer H1 and H2 vehicles. For all model year LLY, LBZ and LMM 2004.5-2010 Duramax Diesel Engines.
