3 Bolt Exhaust Stinger Installation Kit, for Type 1 VW

EMPI 3-Bolt Exhaust Stinger Installation Kit for Type 1 VW (00-3521-0)

Essential Hardware for Your VW Exhaust

The EMPI 3-Bolt Exhaust Stinger Installation Kit (Part #00-3521-0) provides the critical components needed to secure your exhaust stinger or collector to your Type 1 air-cooled engine. This lightweight yet durable kit ensures a tight seal, preventing power-robbing exhaust leaks and keeping your engine running efficiently. It includes high-quality gaskets and the necessary hardware designed specifically for the standard small 3-bolt flange pattern.

Vehicle Fitment & Compatibility

This kit is engineered for the small 3-bolt flange pattern commonly found on high-performance and off-road exhaust systems. It is compatible with Type 1 Volkswagen engines, making it a perfect fit for Beetles, Karmann Ghias, and custom Dune Buggies or Sand Rails. Whether you are replacing a worn-out gasket or installing a fresh stinger for the weekend, this kit provides the reliable seal required for air-cooled applications.

Pro Tech Tips for Installation

Apply Anti-Seize to Threads: Because exhaust components are subjected to extreme heat cycles, bolts can easily seize or "weld" themselves into place over time. Applying a small amount of high-temp anti-seize to the bolt threads during installation will make future maintenance or exhaust swaps much easier and prevent snapped hardware.

Check Flange Alignment and Flatness: Before tightening, ensure that the two mating flanges are flush and parallel. If one flange is warped from previous heat cycles, even a new gasket may struggle to seal. Use a flat file to smooth out any high spots on the header or stinger flange to ensure a perfect, leak-free mating surface.

Use an Even Torque Pattern: To ensure the gasket crushes evenly and creates a permanent seal, tighten the three bolts in small increments, rotating between them rather than tightening one fully at a time. This "star pattern" approach prevents the flange from cocking to one side, which is the leading cause of premature gasket failure and exhaust "popping."
