Stainless Steel Exhaust Header for Honda Prelude (1993-1996) 2.2L

High-Flow Stainless Steel Exhaust Header for 1993-1996 Honda Prelude (BB1)

What it Does: The Stainless Steel Exhaust Header replaces the restrictive factory exhaust manifold on the 1993-1996 Honda Prelude to optimize exhaust gas scavenging and reduce engine back pressure.

The Stock Honda Prelude Exhaust Restriction

The factory cast iron manifold on the fourth-generation BB1 platform features restrictive, uneven runner geometry and rough internal casting surfaces. This design disrupts exhaust pulse velocity and creates excessive back pressure at higher RPM, choking scavenging efficiency right as the H22A1 engages its high-lift VTEC cam profile. In addition, repeated thermal cycling often leads to hairline fractures in aged OEM cast iron manifolds, compromising exhaust velocity and causing pre-converter leaks.

The Engineering Solution

Fabricated from mandrel-bent T-304 stainless steel tubing, this 4-2-1 tri-Y header optimizes pulse scavenging across the mid-to-high RPM range. Smooth 2.00-inch primaries transition into paired secondaries to maintain optimal gas velocity, allowing the H22A1 DOHC VTEC engine to evacuate spent combustion gases rapidly. CNC-machined thick mounting flanges resist warping under sustained thermal loads, while the integrated front pipe flex section absorbs engine pitch to protect downstream exhaust components. Precision-placed pre- and post-catalytic O2 sensor bungs allow plug-and-play sensor integration without custom fabrication.

Frequently Asked Questions & Fitment Warnings

Does this fit the BB1 Prelude?

Yes, this is a direct fit for the 1993-1996 Honda Prelude equipped with the H22A1 engine. This header does not fit non-VTEC models equipped with the 2.2L F22 or 2.3L H23 engines.

Are new hardware and installation gaskets provided with this system?

Yes, the package includes complete mounting hardware along with three direct-fit gaskets to ensure a leak-free seal upon installation.
