Hello Group
I just bought a 96 Suburban 2500 4x4 with the 7.4L and have read about the tuning (Blackbear and Nelsons) and have found headers (Gibson) and exhaust cat backs (Flowmaster & GIbsons) online. Has anyone tried any of these and how did they work out. My truck's main purpose will be towing a 31' travel trailer I have a daily driver.
