TurboXS Turbocharger Outlet Gasket

TurboXS Turbocharger Outlet Gaskets: Precision Sealing for Performance Builds

When you've invested in a performance turbo system, the last thing you want is exhaust gases escaping at the critical junction between the turbocharger and the downpipe. TurboXS — a brand that has been engineering application-specific performance parts since 1999 — takes that sealing challenge seriously with a focused lineup of turbocharger outlet gaskets built to the same exacting standards as their full exhaust and boost systems.

Multi-Layer Steel Construction With a Stainless Fire Ring

What sets TurboXS turbocharger outlet gaskets apart from generic replacements is their engineering approach. Each gasket features a Multi-Layer Steel (MLS) construction, mirroring the design philosophy of OEM gaskets while stepping up durability for high-output applications. Complementing the layered core is a stainless fire ring design that promotes positive sealing against the flange surface, keeping exhaust gases contained exactly where they need to be — inside the system, driving the turbine.

The product lineup covers two of the most popular modern Subaru flat-four platforms. The FA20 Turbo to Downpipe Outlet Gasket (GTO-FA20) is a two-layer design available in either 0.65 mm or 0.5 mm thickness to suit different fitment needs. For owners of FA24-equipped vehicles, the FA24 Turbo to Downpipe Outlet Gasket (GTO-FA24) steps up to a seven-layer stainless steel construction at 0.25 mm total thickness — maximizing compliance and crush characteristics for a robust, leak-free seal on the higher-output engine.

Why Gasket Quality Matters at the Turbo Outlet

The turbocharger outlet is one of the hottest, highest-pressure points in any forced-induction exhaust path. A compromised gasket here doesn't just cause annoying ticking noises — it can allow hot gases to erode surrounding components, skew boost readings, and ultimately reduce the performance gains your entire turbo system was designed to deliver. TurboXS designs these gaskets as direct-fit, application-specific parts rather than universal approximations, which means the bolt pattern, inner diameter, and material thickness are dialed in for the exact flange geometry of each target engine.

Built by a Brand That Knows Turbocharged Platforms

TurboXS has spent decades developing components for turbocharged Subaru WRX, STI, Forester XT, and Legacy GT platforms, as well as Honda Civic, Hyundai, and other popular forced-induction vehicles. That hands-on experience with complete turbo systems — from intercoolers and downpipes to blow-off valves and boost controllers — informs how they engineer even their smallest gaskets. Every spec, from layer count to fire ring placement, reflects real-world knowledge of what these junctions endure under boost.

Whether you're replacing a worn OEM seal during a routine service or upgrading to a more robust gasket as part of a full turbo system installation, TurboXS outlet gaskets deliver the precise fitment and durable construction that performance builds demand.
