About the product
This 4-2-1 exhaust manifold is a CAD-designed T304 stainless steel part. It replaces the restrictive standard cast iron manifold and the catalytic converter with a decat downpipe.
The 4-2-1 design is described as offering greater mid-range gains than a 4-1 design. It has a 2.5-inch bore collector and TIG-welded construction, and is a direct bolt-on fitment to a standard or aftermarket backpipe (centre section). The design improves exhaust gas flow and throttle response, with dyno-proven power gains.
