The GPP RS-Race for the Subaru 08-14 STI and 11-14 WRX hatchbacks is our most aggressive system for the turbocharged EJ25 in the GRB chassis. The RS-Race is ideally suited applications, which require less sound suppression and maximum flow (or customers who just want an aggressive sounding exhaust.) This light-weight, large diameter, full stainless-steel 80mm (3.14”) non-tapered, cat-back exits the (right) passanger-side and has no pre-resonator. Even with the cost-effective price point on the RS-Race, quality materials, construction and craftsmanship is not compromised. For extra customization, the RS-Race Tri-bolt tip allows for installation of optional RS Tip Silencers, various tip lengths and styles in both stainless steel and genuine Titanium.
