3-Bolt High Temperature Exhaust Gasket 2.25In

The 3-Bolt High Temperature Exhaust Gasket 2.25In from Vibrant Performance is a critical sealing component designed to prevent exhaust leaks at the manifold-to-header junction on modern street and performance vehicles. Whether you're rebuilding an engine, upgrading to a new exhaust manifold, or troubleshooting a persistent exhaust leak, this gasket ensures a reliable seal under extreme thermal cycling. Built for 2.25-inch diameter exhaust ports, it's an essential part for any serious engine builder or enthusiast tackling exhaust system work.

Vibrant Performance's high-temperature formulation withstands continuous exposure to exhaust manifold temperatures exceeding 1,200°F, resisting degradation and blow-by that plague inferior gaskets. The three-bolt mounting pattern provides secure positioning and repeatable clamping load distribution across the sealing surface, eliminating hot spots and micro-leaks common with single-bolt or unreinforced designs. The 0.06 lb gasket is engineered with composite materials that compress uniformly under bolt tension, creating a gas-tight seal without requiring re-torquing after thermal cycling—a significant advantage over copper or steel alternatives that can relax at high temperatures.

This gasket is ideal for naturally aspirated and boosted applications where manifold temperatures are consistently high, from street performance builds to road-racing platforms. Installation is straightforward: position the gasket on the three bolt holes, align your manifold, and torque fasteners in a star pattern to manufacturer specifications. Its compact 5.1 x 6.25-inch profile fits standard LS, small-block Chevy, and aftermarket headers with 2.25-inch ports. For anyone replacing a failed gasket or assembling a fresh engine, this Vibrant Performance component delivers the reliability and longevity expected from a purpose-built performance brand.
