IMPREZA EJ20 - SYMPHONY - CFD EXHAUST MANIFOLD

Exhaust manifold from the "CFD" product series. CFD speaks for itself: "Computational Fluid Dynamics" or computational fluid simulations.

The hybrid UNEQUAL length exhaust manifold is designed to retain the distinctive sound of the Subaru boxer engine while simultaneously achieving high-rpm performance (4000 and above). Through computational simulations and by targeting the timely pulse of each cylinder, we achieved the sound of an Unequal length manifold at low RPMs and the behavior of an Equal length manifold at higher RPMs.

A technologically very advanced exhaust manifold for the SUBARU EJ20 engine! Specially developed for power exceeding 500hp. Unlock the potential of your engine!

Option to order with INCONEL thermal protection. Absolutely the most effective thermal barrier on the market. A thermal barrier that is welded using a special process and becomes an inseparable part of the manifold.

Material: Stainless steel - seamless pipes

Pipe diameter: 42.2mm

Wall thickness: 2.77mm

Flanges: 10mm BILLET CNC

*The exhaust manifold is supplied without an UP-PIPE due to countless variations of turbochargers and wastegate valves. UP-PIPEs are custom-made upon agreement with the customer.
