The GPP RS-Race for the 2013-16 Scion FR-S & Subaru BRZ is our most aggressive system we offer for the ZN6 chassis. The RS-Race is ideally suited for turbocharged, race applications (or customers who want an aggressive sounding exhaust), which require less sound suppression and maximum flow. This light-weight, single-sided, full stainless-steel 3.0” (76mm) cat-back RS-Race exhaust exits the (left) driver-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.
