B engine 4-2-1 header specs

Direct-fit 4-2-1 manifold: SUS 304 polished stainless with O2 bung. A b engine 4-2-1 header stages the merge for low-to-mid pull versus a 4-1 top-end layout. It is not the 2.5 4-2-1 sister SKU and not the 4-1 B-engine manifolds.

Install this b engine 4-2-1 header on a cold engine with a fresh b engine header gasket, torque evenly, and re-check after the first heat cycle. Confirm O2 bung position before the road test. Genuine SRS from MCG Autostyling in Kells, Co. Meath with fast delivery across Ireland.

This B engine 4-2-1 header is listed for Honda B-engines 91–02. Confirm exact vehicles on the Fitments tab before ordering.

After install, listen for flange leaks and re-torque cold. Keep heat shields clear of bodywork and fuel lines. Pair with a matching midsection and catback for a full SRS B-series exhaust path.
