Heat-Resistant Exhaust Gasket for Briggs World Formula (Superseded by 691893)

Hot exhaust leaks can sabotage your race—seal them out with the SKU 557047 gasket, superseded by 691893. It clings tenaciously to manifolds, directing every pulse where it belongs for uncompromised flow.

• Multi-Layer Steel: Flexes under torque yet rebounds to block gases up to 1,000°F.
• Port Matching: Exact contours prevent blow-by, sustaining vacuum for torque gains.

The payoff? Cleaner combustion and a freer-revving engine, slicing through wind with less effort. Easy to install during header swaps, it keeps your pit area tidy and your kart primed. For World Formula warriors, it's the quiet guardian of speed.

Feedback from trackside: no more blue smoke or power dips, just steady pulls that build leads. Durable against expansion, it organizes your build for repeated abuse.
