Our new Super-Flow 4" system for your H-1 is designed and engineered to optimize engine output and to deliver an exhaust note that 'fits' the big Hummer. Engine lovers will delight at the big, bold exhaust note and will enjoy the sweet, singing sounds of the turbocharger spooling up and down.
We have thoughtfully designed the system to produce this big, powerful sound while it maintains a quiet passenger cabin. With the windows raised, the interior sound is as quiet as originally intended. Lower the windows and you can bask in the beautiful sounds.
For maximum engine efficiency, complete your H-1's exhaust system with our optional 'Off-Road' pipe. The Off-Road pipe is specially designed to replace that restrictive component located just forward of the factory muffler assembly.

Hummer Exhaust - Added by: Henry
I am positively thrilled with the Heath exhaust system for my Hummer! Now, this rig has a sound that matches its looks! The guys at Heath told me that it would still be quiet inside and that is important to me in my business, which has me hauling business associates. Just like they told me, with the windows up it is no noisier now than before. I lower the left rear window to hear that big-dude sound, when I want to hear it. I can feel a big difference in power and even though I have had it on for only a few days, I can see that my mileage is up already.

I also use Heath's Max-Tork computer, Turbo master boost control and PMD Isolator thing. I could not be any happier with my Hummer---it has power and it sounds great!
