Our Gravity Performance Exhaust Manifolds are designed to create a more free flowing system. The larger 3′ 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 highest quality T304 grade stainless steel
Mandrel bent and fully TIG welded for strength and durability
Designed to maximise the exhaust flow for the D series engines
Fully polished tubular 4-1 design
Directly replaces the standard manifold and fits the OEM downpipe
