Moose Racing Exhaust Gasket for the Suzuki 2000–2024 DR-Z400

The exhaust crush gasket is a critical component designed to create a leak-free seal between the engine cylinder head and the exhaust header pipe. Over time, factory gaskets compress, harden, and degrade due to thousands of extreme heat cycles. Reusing an old gasket during exhaust maintenance or aftermarket header installation often leads to power-robbing exhaust leaks, poor idle, and severe popping on deceleration.

This premium replacement gasket is manufactured from high-temperature copper and composite materials built to withstand intense exhaust heat and vibration. Engineered as a crush-to-seal component, it physically compresses as you torque the header bolts, conforming perfectly to the micro-imperfections on both the cylinder head and the exhaust flange to ensure a permanent, airtight seal.

Features:

• High-Temperature Construction: Manufactured from a blend of copper and heat-resistant fibrous materials capable of withstanding extreme exhaust temperatures without failing.

• Crush-to-Seal Design: Engineered to compress upon installation, filling microscopic gaps between the exhaust flange and engine block for a perfect seal.

• Direct OEM Replacement: Designed to meet or exceed original equipment manufacturer specifications for exact sizing and reliable performance.

• Prevents Exhaust Leaks: Eliminates the lean running conditions, backfiring, and decel-popping associated with a leaking header pipe.
