This Sinister Diesel LMM Duramax EGR Delete Kit is made to fit the 2007.5-2010 Chevrolet 2500 & 3500 HD and is designed to replace your stock EGR Valve and Cooler system, and even includes a mandrel-bent Aluminum intake finished in high-gloss Sinister Blue powder coat. This kit fits the 6.6L LMM Duramax and provides your engine with improved exhaust gas flow, giving you a faster spooling turbo for more power when you need it.

Our Sinister Diesel LMM Duramax EGR Delete is made in-house at our California manufacturing facility from strong nickel plated steel and machined billet aluminum then fully TIG welded and pressure tested to ensure unrivaled durability and leak-free service under the harshest conditions. The Sinister Diesel also improves engine reliability by recirculating your engine coolant faster than the stock EGR system for lower coolant temperatures, and also keeping your intake manifold free from power-robbing, hot, sooty air.

This LMM Duramax EGR Delete Kit with high flow intake has been competition tested to over 700hp making it an ideal upgrade for your high power drag or sled-pull truck!
