These manifolds are ''Pulse'' tuned to assist in combustion chamber evacuation and higher exhaust flow. This results in quicker turbocharger spool up with a decreased amount of backpressure while increasing power and fuel economy. Some kits also include Stainless Steel bolts and washers which help resolve the issue of lost or loose manifold bolts. Gaskets kits are available.
Whether towing or racing, help prevent cracking and leaks while at the same time increasing performance and response with BD's Pulse Manifolds.
