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 )

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 .
