Our Gravity Performance Exhaust Manifolds are designed to create a more free flowing system. The larger Stainless Steel design helps prevent bottlenecks in the Manifold, reducing back pressure in the exhaust system and thus, increasing power from the engine and offering a fruiter exhaust note.

Manufactured from high quality T304 grade stainless steel

Mandrel bent and fully TIG welded for strength and durability

CNC machined flanges for strong, solid support and fit

Free flowing 4-1 Tubular design

Equal length branches for equalizing cylinder pressure
