The stock resonator box on your Chevy or GMC Duramax is bulky and can get in the way when you’re doing any work in the engine bay. The Duramax resonator cover plate from Sinister Diesel allows you to get rid of the stock plastic box and replaces it with an attractive blue plate that not only simplifies the engine compartment, but also lets you hear your turbo spool even better.
