- Patriot Exhaust Weld-Up Header Race Kits
Patriot Exhaust Weld-Up Header Race Kits work great for racers who need to build custom headers when a specfic fit header is not availble. Kits include mandrel bent one piece primaries, two 3/8" precision machined flanges, and your choice of weld-on or slip-on collectors. The unique long transition design of the collectors provides better flow. Mounting bolts, gaskets and collector locking tabs (slip-on style only) are also included.
