Duramax Muffler Delete

September 12, 2020

In this video I show you how to install a MBRP 4″ filter back exhaust in my 2007.5 Duramax GMC Sierra. This install is the same for all 2007 to 2013 Chevy Silverado and GMC Sierra Duramax trucks. I recently purchased my 2007 2500HD GMC Sierra and when I got it home I noticed that the exhaust was all rigged up and not to my liking. So the reason for installing this 4″ MBRP filter back exhaust was just to fix the rear portion of my exhaust. I wasn’t looking to gain any horse power or sound, but I was sure hoping to! Check out the video to see if it changed the sound from deleting the duramax muffler.
