From our family of X-crossovers...3.5" UNIVERSAL X-KIT, ALL ALUMINIZED WITH MANDREL BENT 3.5" ENTRY & EXIT PIPES. TRIM TO FIT YOUR HEADER COLLECTOR C-TO-C.
Recommended for 550hp+ applications.
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!
