Genuine BMW Exhaust Hardware Refresh Kit - 183emsKT - E36, E34, E38, E31

Product Details

Exhaust hardware goes through hell and back with constant heat cycling, moisture, and road debris, often leaving the original studs stripped or seized. Don't compromise your exhaust project with cheap hardware store replacements or warped old fasteners. This Genuine BMW Exhaust Flange Hardware Kit is the exact replacement setup needed to secure the manifold-to-pipe connection. Built to original factory tolerances, the high-tensile M10 studs pair perfectly with the self-locking copper flange nuts to maintain constant clamping pressure under aggressive driving and high exhaust temperatures. It is an essential kit for any track day prep, manifold swap, or downpipe upgrade.

Key Features

• Direct Factory Fitment: Eliminates the guesswork with standard OEM parts designed for high-heat exhaust applications.

• High-Temperature Reliability: Copper lock nuts contract and expand uniformly with heat to prevent backing off or seizing.

• Integrated Collar: Hex nuts feature an integrated collar flange to evenly distribute clamping load without the need for loose washers.

• Essential Service Kit: Ideal replacement hardware for any project requiring the removal of the exhaust manifold or connecting pipes.
