Here's what you've been waiting for. A performance exhaust system designed to work with the advanced emissions control system incorporated into the new GMC/Chevy Duramax trucks. The filter back design connects to the diesel particulate filter (DPF) so there is no risk of triggering sensors or compromising the emission system. From there, MBRP Inc. has improved exhaust flow by reducing bend degree angles and eliminating the stock muffler. Our tests have proven sufficient noise suppression without the stock muffler. Our system tunes the sound to a pleasing growl.
