As with the first generation, the turbocharged STI variants were available in numerous specifications with a myriad of limited edition variants sold. Subaru Impreza issued yearly updates to the STI, tweaking cosmetics and equipment levels, and also improving performance and handling.
At DKU Performance, we custom design the full range of exhausts, from performance back boxes to cat-back exhausts from the entry-level to the premium level, and for the Motorsport players, the awesome tubular manifold back and turbo-back exhaust. They are all custom-made in high-grade 304/316 stainless steel.
