A perfect match to GReddy cat-back exhaust systems and/or GReddy Supercharger Kits. All GReddy headers are made from stainless steel mandrel bent pipes. Great care was taken during the design to enhance the performance of your normally-aspirated or Supercharged vehicle; by fine-tuning the placement; size and angle of each collector to even out the exhaust pulses. Combined with large primary runners make GReddy Headers a solid choice for your vehicle.
Full stainless steel exhaust manifolds
Large primary runners; with tuned lengths & smooth collectors
Ideal for tuned Normally-Aspirated to Supercharged applications
CARB Excempt for many applications Learn More

Vehicles that are already equipped with factory turbochargers have engines with large potential for power that cannot be fully obtained by using the original turbocharger(s). Big gains can be found by upgrading the exhaust; intake; blow-off valve and intercooler and adding more fuel and boost; but by also replacing the stock turbocharger with a properly sized GReddy turbo upgrade kit; you can experience new levels of power. Kits are available for most popular Japanese turbo vehicles; and for many; we offer a selection of kits with various sizes of turbos from mild upgrades to full-on race ready kits. Depending on application; kits will either bolt onto factory manifolds with integral wastegates or use hand-made SUS manifolds with external wastegates. Learn More

The Cosworth Subaru EJ25 CS600 series is designed extreme track use the demanding performance enthusiast. Each assembly is precision built by of Cosworths skilled craftsmen using finest components from parts catalog to ensure maximum reliable power performance. Starting with a Subaru EJ257 semi closed deck block; we meticulously hone each bore to guarantee perfect piston to cylinder wall clearance. block is then assembled with Forged Pistons; motorsport grade Forged H Beam connecting rods along with high performance and main bearings a STI Forged crankshaft. maximum performance; an optional steel billet crank is available (CS600X). Once cylinder block assembly is completed; we install a pair of CNC machine port-bored Valve Cylinder heads with proven S2 camshafts complete with valve lash to specifications. cylinder heads secured with high performance 11mm steel studs sealed with a Cosworth high performance stopper layer steel head gasket. Finally; we install of blue-printed; high pressure pumps maximum lubrication. This proven engine combination been used by teams to events in both North Americaand Europe.

For over 40 years; Cosworth's been leader in innovative multi valve cylinder head design both racing high performance production cars. Cosworth Ported Valve Cylinder head range is latest advancement. Modified from OE cylinder head castings; substantial flow improvements upgraded valve train components offer superior performance your high performance engine.
Each original cylinder head design is carefully evaluated tested to establish improvements required to meet target performance level. Hours of testing flow bench validation used to determine best advanced port design yielding maximum usable power response. However; there is more to cylinder head design than just maximum flow. It is critical that port velocits maintained to ensure drivability valve train components matched to guarantee reliable performance. Once of these factors have been tested validated; final port contour is digitized. Using digitized program; we then reshape both intake exhaust ports using axis mill producing an accurate consistent port shape every time. In addition to reshaping enlarging intake exhaust ports; most Valve Cylinder heads feature a re-shaped combustion chamber to un-shroud valves increasing flow performance. After machining; each cylinder head receives a multiangle high performance valve on precision valve seat cutter. Then each cylinder head is ultrasonically; cleaned; serialized then hand assembled with select high performance valve train components; ready to install on your engine.
