97-01 Mitsubishi Mirage Aluminum Exhaust Header Gasket

Will I need new bolts to install this, or can I reuse my factory hardware?

Reuse your factory header bolts and washers—they're fine. Just clean the mating surfaces with a wire brush before fitting the gasket, and torque them snug in a cross pattern to avoid warping.

Can I install this myself with basic hand tools?

Yes. You'll need a socket set and wrench to unbolt the header, pull the old gasket, and bolt the new one down. No special equipment or gasket sealer required—aluminum-to-aluminum seals dry.

What's the difference between this and a stock composite gasket?

Stock gaskets swell and crack from repeated heating and cooling. Aluminum won't do that. You're buying durability against thermal cycling—especially valuable if you run headers regularly or plan any engine work.
