The 4-2-1 Manifold is designed to allow the exhaust gasses to flow quicker through the manifold. The Small bore manifold is suitable for Lotus Elise’s with up to around the 185-190bhp mark, but once your engine is achieving in excess of 190bhp it is recommended you use a larger bore manifold. PTP are now able to offer a large bore manifold for the S1 and S2 Lotus Elise with the K Series engine.

The manifold is a direct replacement part for the standard down pipe and manifold and produced in a high-grade stainless steel with all brackets and clamps needed for fitment.

The Janspeed 4-2-1 exhaust manifold and link pipe have been specifically designed for all models of the S1 & S2 Lotus Elise (K Series engine) including vehicles with air conditioning. Produced in high-grade stainless steel with a lifetime guarantee, the manifold is supplied with all brackets and clamps needed for fitment without any need for body modifications.
