Exhaust Header Manifold for 1962-1974 MG MGB 1.8L | SPELAB

This SPELAB stainless steel exhaust header is designed for compatible 1962-1974 MG MGB 1.8L applications and is intended for owners replacing an aging manifold or completing a street-oriented exhaust refresh.

Factory Manifold vs. SPELAB Header vs. Custom Vintage Race Header

A factory manifold suits originality-focused restoration, this stainless header suits a street-oriented refresh, and a custom header may suit a specialized vintage race engine. No fixed power gain is guaranteed.

Why Upgrade Your MG MGB Exhaust Header?

A replacement header can restore a sealed exhaust path when the existing manifold is damaged. Sound and performance depend on the carburetors, ignition, engine condition, downstream exhaust, and installation.

Built for Classic MGB Owners

The product is intended for owners balancing classic appearance, practical road use, serviceability, and a cleaner exhaust-side refresh.

What Makes This MGB Header Different?

Vehicle history matters: engine swaps, steering conversions, prior exhaust fabrication, and restoration work can change fitment.
