Purpose built stainless steel equal-length manifold.

Our manifold is 2″ schedule 10 stainless steel, equal length. This is crucial to maintain even exhaust gas temperatures and controlling boost. Runner length and diameter have been calculated from years of testing and experience. Our manifolds are tuned to the exhaust pulses of the 2 rotor engine.


Stainless steel downpipe

Our downpipe has minimal bends and incorporates a flex section to alleviate stress on the manifold and rest of the exhaust system while ensuring a good fit with the variety of midpipes available on the market.

Oil and coolant lines

DEI heat sleeving is included in every kit for protection and heat management.
