Description

Upgrade your 2007.5–2010 Chevy Silverado or GMC Sierra 2500/3500 HD 6.6L Duramax LMM with this 4″ DPF, EGR & CCV Delete All-in-One Kit . Built from premium T-409 stainless steel , this downpipe-back exhaust system is engineered to deliver maximum performance, durability, and efficiency. Paired with the powerful Mini Maxx V2 Delete Tuner , this kit eliminates restrictive factory emissions systems including the DPF, EGR, CCV, and catalytic converter , giving your Duramax engine the airflow it needs for increased horsepower, torque, and throttle response. By reducing exhaust backpressure, it lowers exhaust gas temperatures (EGTs) , keeps coolant temps cooler by bypassing the EGR cooler, and helps prevent soot from entering your turbocharger—extending engine life. This free-flowing exhaust not only improves efficiency but also enhances fuel economy, with many drivers reporting noticeable MPG gains. OE-style hangers ensure a secure fit and simple installation, typically done in about an hour with basic tools. A muffler option is available for those who prefer a quieter exhaust note.
