X Pipe 3in

The X Pipe 3in from SCHOENFELD is a universal crossover exhaust manifold designed to merge dual exhaust streams into a single output, making it essential for street machines, race cars, and performance-built engines seeking improved scavenging and balanced exhaust flow. Whether you're running a carbureted big-block or a modern fuel-injected platform, an X-pipe configuration eliminates the dead spots created by traditional H-pipes and Y-pipes, allowing each cylinder bank to benefit from pulse energy across the entire rev range.

This 3-inch bore design suits mid-range displacement engines where flow efficiency and simplicity matter most. Constructed with mandrel-bent tubing precision, the X Pipe 3in maintains consistent diameter throughout its crossover path, preventing turbulence and backpressure spikes that rob horsepower. The X-configuration geometry allows opposing cylinder banks to share scavenging pulses, creating a self-cleaning effect that reduces carbon buildup and improves volumetric efficiency—critical for naturally aspirated applications where every cubic foot of air matters.

At 2.87 lbs, this component is compact and lightweight, measuring 14.05 inches in length, making it compatible with tight engine bay layouts common in street rods, classic muscle cars, and modern performance builds. Mechanics and fabricators favor SCHOENFELD's X Pipe 3in for engine swaps where OEM dual-exhaust manifolds don't fit or when upgrading to a more efficient exhaust system from the ground up.
