  1. X-1  2.5" X-Crossover Kit

    X-1 2.5" X-Crossover Kit

    $199.00

    2.5" X-crossover junction with 2.5" mandrel bent entry and exit tubes. Universal for all dual exhausts. Requires trimming, clamp or weld.

    Recommended for all applications to 450hp.

    Our X crossovers will deliver bigger torque gains (better acceleration)than any other system or other brand X and we've proven it on the dyno! Our X-crossover features a research-driven design which splits the exhaust into two equal sub-pulses. This is where other brands fall short. On a mild-built big-block we made 10-15ft/lbs more torque than competitors' X. That difference grows with more radical build. More torque than running open headers!. Learn More
