DynoVox’s catalog of Duramax performance upgrades includes essential delete kits and tuning components that target common factory restrictions. Our EGR and DPF delete kits improve exhaust flow, reduce soot buildup, and prevent premature engine wear. CCV reroute systems help eliminate oil vapor intrusion into the intake system, protecting your turbo and extending engine life. Up-pipes and downpipes are engineered to reduce exhaust gas temperatures and enhance turbo efficiency, while handheld tuners allow for real-time calibration of engine parameters, unlocking gains in horsepower, torque, and fuel economy.
