The best GReddy parts for a WRX or STI are the Supreme SP cat-back exhaust and the Type-S blow-off valve — both deliver the brand's signature Japanese-built quality with straightforward bolt-on fitment. GReddy's catalog covers the full spectrum of forced-induction upgrades, from blow-off valves and exhaust systems to magnetic drain plugs and radiator caps.

GReddy is one of Japan's original aftermarket performance brands, and its lineup reflects decades of turbocharged-car focus. The catalog on this page includes universal blow-off valves like the Black BOV, application-specific valves and springs, Supreme SP cat-back systems for the 15-21 WRX/STI sedan, Type-S radiator caps, and Magdrain magnetic oil drain plugs in M16, M20 and M12 thread pitches. Whether you are chasing sound, reliability, or small details that make a build feel finished, GReddy parts fit the bill without custom fabrication.

Shopping by category? Browse our Subaru WRX blow off valves, performance turbochargers, and performance intercoolers collections for parts that pair naturally with a GReddy setup. Popular picks here include the GReddy Supreme SP Cat-Back Exhaust, the GReddy Black Blow Off Valve, and the GReddy Magdrain Magnetic Oil Drain Plug. Read why an aftermarket exhaust system is worth the investment before you buy.

Do GReddy exhausts bolt up to my factory downpipe?

The Supreme SP cat-backs listed here are designed for stock-location fitment on the listed WRX and STI sedans. Check your year and model in the product title before ordering, since flange styles changed between generations.

Do I need a tune for a GReddy blow-off valve?

Most Subaru owners run vent-to-atmosphere or dual-port valves without a dedicated tune, but a plumb-back valve keeps the factory recirculation strategy. If you are already tuned, ask your tuner — some prefer the plumb-back style for drivability.

Will the Magdrain plug fit my car?

GReddy makes Magdrain plugs in M16 x 1.5, M20 x 1.5 and M12 x 1.25 threads to cover most Subaru, Toyota and Honda applications. Match the thread pitch in the product title to your oil pan — when in doubt, check your year and model.

Is GReddy quality worth the price over generic parts?

GReddy parts are built to consistent tolerances with proper hardware and documentation, which is why the brand has stayed relevant for decades. Fitment and finish are a step above no-name alternatives, and warranty support goes through an established brand.
