COMPATIBLE: (1.8L - B18B1)

1994 - 2001 ACURA INTEGRA

The exhaust header is designed for the 1994-2001 Honda Acura Integra LS/RS with the B18B1 1.8L engine, offering a significant performance boost. Crafted from high-quality stainless steel with a mirror polish surface, this 4-1, 1-piece JDM Type-R Style Integra header enhances exhaust flow, improving engine efficiency and power. With a 2.5" outlet diameter, it’s built for both performance and durability.

From the factory, the Acura Integra B18B1 uses a cast iron exhaust manifold designed for quiet operation, emissions compliance, and low manufacturing cost rather than performance. Upgrading to performance integra headers improves exhaust flow efficiency and unlocks power restricted by the stock setup. Restricted Exhaust Flow: Factory manifolds limit exhaust flow at higher RPM, reducing the engine’s power potential. Improved Exhaust Scavenging: Aftermarket B18B1 headers help clear spent exhaust gases more efficiently between combustion cycles. Reduced Back Pressure: Improved flow allows the engine to rev more freely with quicker throttle response. Supports Additional Upgrades: Enhanced exhaust flow improves the effectiveness of intakes, cat-back exhausts, and ECU tuning. For Integra owners seeking noticeable performance gains without opening the engine, upgrading to a quality exhaust header remains one of the best power-per-dollar modifications available.
