Exhaust Header for Honda S2000 (2000-2009) 2.0L 2.2L

High-Flow Stainless Exhaust Header for 2000-2009 Honda S2000

What it Does: The Performance Stainless Exhaust Header replaces the restrictive factory exhaust manifold on the 2000-2009 Honda S2000 to optimize exhaust gas scavenging, reduce backpressure, and improve high-RPM airflow.

The Stock Honda S2000 Exhaust Restriction

While the OEM manifold on the AP1 and AP2 chassis flows adequately for a factory baseline, thermal fatigue over years of operation leads to stress fractures, internal baffle degradation, and loose heat-shield rattles. Furthermore, the stock primary tube routing generates exhaust pulse collision prior to the merge collector above 6,000 RPM, increasing parasitic pumping losses precisely when the VTEC high-cam profile demands rapid cylinder evacuation.

The Engineering Solution

This direct-replacement header is built with mandrel-bent stainless steel primary tubes that maintain a uniform internal cross-section throughout each bend. Precision-welded, thick-machined head and collector flanges prevent thermal warpage under intense track exhaust gas temperatures (EGT). By balancing primary runner lengths and streamlining collector geometry, this manifold smooths wave scavenging to evacuate spent exhaust gases faster from both the F20C and F22C1 combustion chambers, yielding crisper throttle response and broader mid-to-high band torque.

Frequently Asked Questions

Does this fit the AP1 and AP2 S2000?
Yes, this is a direct fit for the 2000-2009 Honda S2000 equipped with either the 2.0L F20C or 2.2L F22C1 engine.

Will this header trigger a Check Engine Light (CEL)?
No, the manifold retains standard oxygen sensor bung positions for factory primary sensor integration without causing DTC faults.

The Honda High-RPM Standard

Engineered for high-revving naturally aspirated JDM performance, this manifold delivers the thermal durability, exhaust pulse velocity, and unrestricted acoustic tone demanded by 9,000 RPM track and street applications.
