X-275/ULTRA IROC-Z Header Build

Anthony P from Connecticut whipped up this nasty set of big tube small block headers for this '89 IROC-Z Camaro, with the intentions of using it for X275/ULTRA and local small tire race events. This wicked set of fender exit headers are built from 2" primary header tubes, and collecting through one of our performance merge collectors, sized at a 3.5" choke, and transitioning out to 4" on the outlet. The car sports a 385 cubic inch small block and pushes power through an ATI PowerGlide Trans, a 9" Moser rear end, and throws a big fat shot of nitrous on the top end for good measure.
