Performance Exhaust manifolds are a vital part of your vehicles exhaust. Designed to be a direct replacement for the OEM part our performance manifolds are designed to extract maximum power from your engine. Perfectly mated to the engine exhaust ports for smooth gas flow and tuned to your engine displacement and power band characteristics.
Manufactured from highest quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability Free flowing tubular manifolds designed to complement the S54 engine Designed to improve power and torque across the entire RPM range Fully polished with 2.25" exits to fit the OEM exhaust system
Manufactured from highest quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability CNC machined flanges for strong, solid support and an accurate fit Designed to be a direct replacement for the OEM manifold Intended to be as free flowing as possible
Manufactured from high quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability Free flowing to fit the X14, C14 and C16XE engines Designed to improve power and torque across the entire RPM range Free flowing 4-1 tubular design getting exhaust gasses out smoothly
Designed to reduce the restriction from the OEM cat to provide improved gas flow and therefore increase horsepower capabilities Mandrel bent and fully TIG welded for strength and durability CNC machined flanges for strong, solid support and an accurate fit Designed to improve power and torque across the entire RPM range Direct replacement for the OEM manifold setup, with gaskets included
Manufactured from high quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability Free flowing tubular branch manifold to fit a T3 turbo flange Fully polished to compliment the legendary RB engines Supplied with all gaskets and fixings pictured
Manufactured from highest quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability Free flowing tubular design getting exhaust gasses smoothly to the turbo Fully polished with equal length branches to the turbo Noticeably improves throttle response
Gravity Performance manifolds are designed to be direct replacements for OEM manifolds, ensuring smooth installation every time. Our manifolds improve the collection of gasses from the cylinder heads, before routing them through them to the rest of the system. Manufactured from highest quality T304 grade stainless steel Mandrel bent and fully TIG welded for strength and durability CNC machined flanges for strong, solid support and an accurate fit 4-1 design for maximum gains at the top end of the rev range Direct replacement with both gaskets included
