All complete systems includeRA flanges & your choice of mufflers (Goerlich, or SpinTech..see muffler section for details), 4 clamps & hangers & install instructions. (a word about flanges: we make the strongest and best fitting flanges in the market. Cost of poor quality is poor fit...case-in-point: the oversized flanges available from our competitors and also in aluminum. If they don't break the oversized corners may hit the frame in various applications )

Systems with x-over include ball & cone connectors (a needed item for x-systems...position ahead of mufflers). Mandrel bent headpipes and x-over tubes.

Only superior RARE x-over components are used in our systems! Our X-crossover creates more torque on same car test than all the other brands which are merely 2 elbows welded together. Our X is designed by Nascar and OEM GM supplier .

Tailpipes are thick-wall 14 ga. aluminized steel or mandrel bent 16ga.

All components are made in the USA. Learn More
