| Arguably the most amazing hot rod to ever exit a Ford factory, the Shelby GT500 rules the roost with a mountain of horsepower just waiting to be unleashed, American Racing Headers’ bolt in long tube header systems can increase power and torque by as much as 40RWHP and 40RWTQ. Like all American Racing Headers systems, construction is all 304 S/S, flanges are 3/8" laser cut and collectors are merge style and incorporate scavenger spikes. X-Pipe or optional H-Pipe includes Severe Duty 200 cell high flow metallic cats that are 49 State Legal or can be ordered without cats. 1-7/8” headers come standard but for high boost race or street applications, we recommend our 2" primaries with 3-1/2” collectors. Tell us what your performance goals are and we will help you select the perfect set up.
Note: 2" Shelby GT500 Headers For Max Effort Applications. Not Available With Cats
