Custom made, stainless steel, ceramic coated exhaust manifold is available for SAAB 9000 four-cylinder versions!
Allowing quicker evacuation of exhaust gasses from the cylinders as well as separation of gas flow until reaching the collector, all resulting in a significant improvement in spool-up. Reduced back pressure also allows higher top-end when fine tuning boost and ignition maps. The end result is a very high degree of driveability even with very large turbochargers. Strongly recommended combining this with a large downpipe to optimize flow all the way through, and recommended for the street, stock versions as well. Due to the inside and outside ceramic coating the manifold is recommended up to 1200 degree Celsius, holds 30% of the heat.
