Quality -- a simple word with not-so-simple implications. After sending that $800 monthly payment in the mail every month for our luxury SUVs, we don't want to add cheap parts to it when improving the ride, handling, and performance of our daily drivers. When it came time to install an exhaust system on one of our '03 Hummer H2s, we called upon one company where quality is a given -- B&B Exhaust. Quality was evident as soon as we opened the box. Manufactured from T304 stainless steel, the entire system was polished to a shine ending with two 4-inch double-wall tips. This kit is a true dual exhaust with 2-1/2-inch piping from front to back. After 30 minutes, we fired up the H2 to a noticeable grumble that sounded as though the 6.0L actually had some gutsy performance. We traveled to Westminster, California, to CTL Motorsports for the photoshoot, and the crew had us out of there in less than 45 minutes. Trust us, when we say these guys know Hummer H2s, and tell them we sent you. Follow along as we take you through the simple install of this quality system.

Our H2 had the dual pipes cut off with two polished tips exiting the rear. Whereas this made it look better, it did nothing for sound or performance improvement with the restrictive stock muffler.

Two large tips provide the exit for the nice exhaust note and are double-walled to ensure long life. At $850, the kit is not inexpensive, but we know we won't have to worry about it for as long as we own the H2 with a factory-written lifetime warranty.
