PulseFlow Exhaust Manifolds
ATS Pulse Flow Exhaust Manifolds offer far less restriction than stock manifolds and up-pipes. The single most restrictive point in the exhaust system is the first section that it hits, the exhaust manifold(s). We increase the internal diameter 30% in critical areas to allow for decreased back-pressure and allow those gases to drive the turbo. Not only did we increase flow, be we also made the made them out of High Silicon Molybdenum (HSM), a metal alloy that is vastly stronger than the stock cast manifolds. Those areas that are prone to cracking and no longer a problem.
