Popular TurboXS Products

The TurboXS product lineup includes recirculating and atmospheric blow-off valves compatible with the Subaru EJ and FA series engines, top-mount and front-mount intercooler kits for the WRX and STI, high-flow turbo inlets and charge pipes, race downpipes with high-flow catalytic converters, and boost controller kits for managing boost pressure on modified turbocharged applications. TurboXS has been a trusted name in the Subaru performance community for over two decades.

What vehicles does TurboXS support?

TurboXS specializes in parts for the Subaru WRX and STI across multiple generations including the GD, GR, VA, and VB chassis, as well as the Subaru Forester XT, Legacy GT, and Outback XT turbocharged models. The brand also offers products for the Mitsubishi Lancer Evolution and select turbocharged Volkswagen and Audi applications. Fitment guides are available for each product to confirm compatibility with specific model year and engine combinations before purchase.

Are TurboXS parts street legal?

TurboXS offers both street-legal and track-only variants of their performance components. Downpipes are available with high-flow catalytic converters for emissions compliance on street-driven vehicles, and without catalysts for race-only use. Blow-off valves in recirculating configuration maintain emissions compliance on vehicles that do not allow atmospheric venting. Always verify the specific product variant's emissions status against your local regulations before purchase.
