H2 Hummer Bolt-on Shorty Header

 

 

BREATHLESS PERFORMANCE PRODUCTS-  Through Our Endless Effort and Continuous Testing of Other Brands of Headers We Came Up With Some Changes That We Felt Necessary.

This Custom Header  1.5/8 header  Produces low to mid power Torque and HP.   Both Bottom end and high are increased due to this design. This is a direct bolt-on header which takes about 4 hrs to install. With higher efficiency in the bottom to mid rpm range fuel mileage is also increased. Dyno results of shorty headers produce between 10 to 35 Horsepower depending on other mods in the engine.  

Collectors are  2.1/2 . We have also taken the time and effort to jet coat both inside and out of the header. Jet coating provides cooler engine bay temps and that nice shinny clean look which will never change colors.

We Fully Jet Coat Our Headers Inside and Out.

Dyno results have shown between 10 to 35 HP gains depending on engine mods.
