The performance exhaust manifold replaces the standard down pipe and cast manifold.  With its free flow large bore tubing extra power is produced by allowing the gases to escape more quickly.  For maximum power combine this product with a full performance exhaust system and an induction kit.  Being close to the engine the performance exhaust manifold has to cope with immense heat from internal combustion.  To protect other engine bay components the 4 branch is sometimes equipped with a metal heat shield.  Manifolds can be painted with high temperature paint or wrapped with exhaust wrap for additional under bonnet heat control.  Our performance exhaust guide gives further information.  Our range covers 4 branch manifolds made by Piper, Sportex, Supersprint and Milltek.
