Map options for Stage 2 maps currently include: Stock intake (Including COBB), ETS intake, and Perrin Turbo Inlet, but check back soon for more options.

Please note that some aftermarket catted J-pipes may not satisfy the factory catalyst monitor logic, and as such, vehicles running this map may be subject to a check engine light after 2 or more drive cycles. The most common code related to catalyst monitoring is the P0420 code but you may also see P2096, P2098, and others related to the rear O2 sensor. Codes cannot be fixed via tune processes and will require mechanical changes to satisfy the vehicles onboard readiness monitor system. Codes can be scanned and cleared via the Cobb Accessport device. On the Subaru platform, a DTC will cause all other malfunction lights on the dash to illuminate such as ABS, TCS, and Cruise Control but does not indicate an actual problem in these systems.
