Greddy

GReddy is the performance brand of Japan’s TRUST company, which was founded in 1977. Its American operation, GReddy Performance Products, opened in 1994 and is based in Irvine, California. If you’ve seen both TRUST and GReddy names on Japanese performance parts, that’s the connection. They belong to the same company’s history.

The lineup covers exhaust systems, turbo kits, intercoolers, oil coolers, intake components, and engine electronics. Exhaust lines such as Supreme SP, Revolution RS, and Evolution GT are part of that catalog, alongside the supporting components needed for more involved builds. GReddy calls this its “Total Tune-Up” approach, developing parts with the rest of the vehicle’s modifications in mind.

There’s some memorable car history behind the name, too. When GReddy opened its Irvine headquarters in 1995, the company brought its GReddy RX R32 GT-R over from Japan for the grand opening. Today, the catalog still supports platforms such as the SR20-powered S-Chassis, RB26 GT-R, and 2JZ Supra alongside newer cars like the GR86 and Civic Type R.

Why We Like GReddy At 9AM:

We like seeing continued support for the older Japanese platforms we care about. An exhaust is one part of a build, but oil cooling, intercooler plumbing, and the smaller supporting pieces matter too. GReddy’s catalog reflects that, and the connection to Japan’s tuning history gives the brand a story we enjoy just as much as the parts.

Exhaust Systems

GReddy exhaust systems are a natural starting point for a street or track build. They offer vehicle-specific systems for a wide range of Japanese platforms, giving owners a way to change sound and flow without turning the exhaust into a completely custom project.

Intercoolers & Cooling

Once boost and heat become part of the equation, cooling starts mattering quickly. GReddy intercoolers and related cooling components have long been a common upgrade for turbocharged Japanese performance cars.

Turbo & Forced Induction

GReddy built a huge part of its reputation around turbocharging. Their forced-induction products make the most sense once the build has moved beyond simple intake and exhaust upgrades and you're planning the supporting fuel, cooling and engine-management pieces around the complete setup.

Engine & Performance Accessories

GReddy also offers the smaller pieces that tend to show up as a build progresses, including gauges, electronics, cooling components and other supporting hardware.
