X-Pipes

Balance exhaust gas pulses, maximize high-RPM scavenging, and achieve an exotic, race-inspired exhaust tone with performance X-pipes. Positioned at the crossover junction of dual exhaust systems, an X-pipe forces exhaust streams from opposing cylinder banks to intersect at a precise crossover point. As high-velocity exhaust pulses pass through the "X" junction, a natural vacuum effect is created that actively pulls spent combustion gases out of the opposing cylinder bank—reducing internal backpressure and improving engine efficiency.

Compared to traditional H-pipes or straight-pipe setups, X-pipes deliver superior high-RPM horsepower gains and a higher-pitched, raspy exhaust note. Whether you're replacing a restrictive stock crossover on a V8 muscle car, building a custom dual exhaust layout for a street build, or optimizing airflow for track days, an X-pipe provides essential pulse equalization. Explore mandrel-bent T304 stainless steel and aluminized steel X-pipes in universal weld-in and direct bolt-on configurations across 2.25-inch, 2.5-inch, 3-inch, and 3.5-inch exhaust pipe diameters.
