Agency Power saw a need for a complete exhaust upgrade for the newly redesigned Subaru WRX and began testing. The new body style featured a completely new power plant, FA20DIT, to supply energy to the four wheels. But like most factory exhaust systems, they lack performance, sound, and tend to be very restrictive.
Starting from the front of the vehicle we designed a much better free flowing turbo manifold. Utilizing 1.5” schedule10 thick-wall stainless steel, we were able to maximize heat absorption and heat dissipation, while still being strong enough to support the weight of the turbo. The new flanges were water jetted out for precise fitment to ensure leak free junctions, 3/8” thick at the turbine side of the manifold and 1/4” thick at both exhaust port banks.
