Tegiwa Header 4-2-1 – Stainless Steel – Honda Civic, CRX, Del Sol (B-series)

Built for power, made for clearance

The Tegiwa 4-2-1 Header is a serious upgrade for any post-'92 B-series build. Constructed from 304-grade stainless steel, TIG-welded with precision, and featuring a true 2.5" collector, this manifold brings dyno-proven gains and unbeatable road clearance.

Compared to OEM JDM 98 spec headers, it gains +7.2 bhp and +0.9 ft/lbs. Against earlier UK-spec manifolds, it nets up to +12 bhp and +7 ft/lbs torque. And at only 5920g, it’s a lightweight win too—shaving over 2.3kg vs JDM and more than 9kg vs cast units.

Perfect for Civic, CRX, and Del Sol with B-series engines (post-1992). One oxygen sensor port included. Earlier B-series models may require a second sensor port modification.

To fit this header, a 2.5" CAT or decat pipe is required.
