This Sinister Diesel LML Duramax EGR Delete Kit is designed for the 2011 to early-style 2015 Chevrolet 2500 & 3500 HD and takes the place of your stock EGR Valve and Cooler system. This kit provides the 6.6L LML Duramax engine with improved exhaust gas flow for faster turbo spool and lower intake temperatures, giving you more power right away.

Our Sinister Diesel LML 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.
