EMPI Premium Header Installation Kit for Type 1 VW

Product Overview and Fitment

The EMPI Premium Small 3-Bolt Header & Muffler Installation Kit (Part #00-3637-0) is a comprehensive hardware solution designed for air-cooled enthusiasts seeking a leak-free exhaust seal. This kit is specifically engineered for VW Type 1 engines, commonly found in the Volkswagen Beetle, Karmann Ghia, and Type 181 Thing. It is compatible with any aftermarket header and muffler combination that utilizes the standard small 3-bolt flange connection.

Unlike standard kits, this premium version features steel-clad gaskets for the cylinder heads to provide maximum heat resistance and longevity. The kit includes the 3-bolt flange gasket, stainless steel Allen bolts, copper nuts, and specialized paper gaskets for the intake heat risers.

Pro Tech Tips from Appletree Auto

1. Leverage the Copper Advantage: Always use the copper nuts provided in this kit for your exhaust flanges. Copper is naturally resistant to seizing and "galling" under extreme thermal stress. By using these instead of standard steel nuts, you ensure that the hardware can be removed easily in the future without the risk of snapping studs or needing to drill out frozen bolts.

2. Verify Flange Flatness: Before installing the premium steel-clad gaskets, use a straight edge to check that your header and muffler flanges are perfectly flat. Over time, heat can cause flanges to warp slightly. If they are not true, the gaskets may not seat correctly. If necessary, a quick pass with a flat file can ensure a perfect mating surface for a permanent, blow-out proof seal.

3. Don't Overlook the Heat Risers: When installing the thick paper gaskets for the heat riser tubes, ensure the manifold surfaces are scraped completely clean of old carbon and gasket residue. A leak at the heat riser not only creates noise but can also lead to "icing" on the intake manifold during cold weather, as the exhaust gas will not circulate properly to pre-heat the fuel mixture.
