The GPP RS-Race for the 2015-on Subaru WRX/STI is our most aggressive looking system for the VA sedan chassis. The RS-Race is ideally suited applications, which require less sound suppression and maximum flow. (with the factory catalytic converter, this application has a surprisingly mild sound level for cruising and a good rumble under wide open throttle.) This light-weight, large diameter, full stainless-steel 80mm (3.14”) non-tapered, cat-back exits the (right) passenger-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.
