Leading A-Series engine specialist since 1981
Maniflow's latest ST3 large-bore LCB exhaust manifold is ideally suited to 1275-based racing engines.
All primaries now have extra large radial bends from the manifold face to aid gas flow. Both outer primaries are 1.5-inches in diameter, extended in length, which in turn gives a broader power band.
The centre primary has an enlarged 1.75-inch diameter pipe that creates a vortex, simulating a pulsing effect similar to the outer primaries.
The manifold face is matched to the large bore gasket size, making this an ideal match for our race-specification cylinder heads.
If you're looking for a complete exhaust system for a competition Mini, the two-inch RCM Race Exhaust is the perfect match for this manifold.
