TurboXS Exhaust Pipe Spacer

TurboXS Exhaust Pipe Spacers: Precision Fit for Performance Exhausts

When building or maintaining a performance exhaust system on a turbocharged Subaru, the details matter just as much as the big-ticket components. TurboXS has been engineering application-specific performance parts since 1999, and that same precision carries through to their exhaust pipe spacers—small but critical components that keep your exhaust system sealed, aligned, and leak-free.

The TurboXS 63mm Stainless Steel Spacer Gasket

The flagship TurboXS exhaust pipe spacer is their 63mm ID, 2-Hole, 304 Stainless Steel Spacer Gasket, purpose-built for the 2002–2007 Subaru WRX and the 2004–2007 Subaru WRX STI. Unlike generic exhaust spacers that rely on approximate fitment, this component is a TurboXS-designed part engineered specifically around their own exhaust systems and the OEM flange dimensions of these platforms. The result is a precise, repeatable seal that holds up under the thermal cycling and vibration demands of a turbocharged drivetrain.

Constructed from 304 stainless steel, the spacer resists corrosion and heat degradation over the long term—a key consideration given the extreme temperatures generated in the exhaust path of a boosted engine. The 2-hole bolt pattern matches the factory and aftermarket flange layout used throughout the WRX and STI exhaust architecture, making installation straightforward whether you’re fitting it as part of a full turbo-back system or replacing a worn piece in an existing setup.

Why the Right Spacer Gasket Matters

An exhaust pipe spacer serves a deceptively important role: it bridges small gaps between mating flanges, maintains proper pipe alignment, and creates the clamping surface needed to prevent exhaust leaks. On turbocharged applications like the WRX and STI, even minor leaks upstream of the O2 sensor can affect fueling and boost response. Using a correctly spec’d stainless spacer—rather than a mismatched generic substitute—ensures the joint seals correctly the first time and resists warping under heat.

TurboXS designed this spacer to complement their own turbo-back and catback exhaust systems, but it also serves as a reliable repair or replacement part for those running mixed-brand setups who need a quality stainless solution at the 63mm junction point.

Trusted Engineering Across the Exhaust System

TurboXS’s approach to exhaust hardware reflects their broader philosophy: build every component, down to the smallest gasket or spacer, with the same attention to material quality and dimensional accuracy as their full exhaust systems. Whether you’re assembling a complete performance exhaust or simply replacing a degraded spacer gasket, TurboXS delivers a part engineered for the specific application—not adapted from a universal catalog.
