The Gibson dual extreme cat-back exhaust for 2007–2010 Hummer H3 is a stainless dual-system aimed at drivers who want aggressive sound and bold looks. This bolt-on system exits behind the rear tires at an angled position and is dyno-tuned to deliver substantial gains—about 15–20 hp on average—while producing a mean performance tone. It includes polished stainless tips, a Superflow CFT muffler, stainless mandrel-bent tubing, clamp-on tips, hardware and a lifetime limited warranty.
