2017 WRX STI Accessport Available NOW! Plus STI Stage 2!
Cobb Accessport V3 Support on 2017 WRX STI
The 2017 Subaru WRX STI is now supported by the COBB Accessport! All SUB-004 Accessports with qualifying firmware will now be compatible with the 2017 WRX STI. Stage 1 and Stage 2 configurations are supported via Off The Shelf Maps (OTS Maps). Additional Off The Shelf Maps and associated Power Packages will be available in an additional upcoming release. In the meantime, vehicles with modifications beyond Stage 2 can visit a COBB Authorized Protuner for a custom tune.
The COBB Stage 2 Power Package is a simple bolt-on and tuning solution for your 2015+ STI! You get the Accessport tuning convenience, a big increase in power and torque from a free-flowing turbo-back exhaust, and a Stage 2 tune! Listen to the intoxicating rumble of the Subaru boxer engine as it emits through our beautiful 3" Stainless Steel exhaust. Finish off the installation with a Stainless Turbo Heatshield. Your Subaru will love you for it!
