Purpose built stainless steel equal-length manifold.                                                                                                                                                                                                                         

Our manifold is 2″schedule 10 stainless, 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.

Gaskets and hardware                                                                                                                                                                                                         We include Inconel gaskets and locking hardware required for installation of the turbo kit.

Fits a wide range of stetups                                                                                                                                                                                               Most stock mount, front mount, or vmount intercoolers.                                                                                                                                                             Plenty of room for an idler pulley.

Guaranteed to outperform anything else comparable on the market.

Proudly made in the USA by rotary enthusiasts for rotary enthusiasts.
