The Subaru Impreza STi Spec-C is a special, unique car.
It is equipped with a 2.0l engine, which is tuned to deliver higher performance than the larger 2.5l powerplant found on the standard Impreza Sti.

This is mostly due to the increased efficiency of the twin-scroll turbo charger.
Since the day it had been introduced to the public, Supersprint has been offering the perfect, oversize diameter exhaust setup for its Rally race-bred engine, which can be easily modified to reach 400 Hp.
Our Turbo Downpipe uses a HJS Motorsport, high volume, free-flowing metallic catalytic, with smooth merging cones, a mid pipe, plus a large volume rear muffler with straight-through, 76mm inner perforated core (no baffles).
Alternatively, we offer a straight, catless downpipe as well.
We guarantee big power, a huge gain torque, and an amazing sound, with no obnoxious droning in the low rpm range.
Over the years, the Impreza Sti Spec-C, also known as a.k.a. RA R, has grown into cult-car status; the Supersprint exhaust is still the best complement to it.
