Premium cast and perfect fitment Exhaust Manifold D5S 1,8T 20V top mount D5S cast iron top mount manifold Premium cast and perfect fitment Perfect piping ways, perfect casted tip, extra big inner diameter, more flow. Perfect for big turbo upgrades. This cast iron exhaust manifold is manufactured of D5S. The manifolds are engineered using sophisticated software simulating flow, mechanical and thermal stress to ensure maximum reliability and optimum performance. Additionally, prior to being sold the manifolds are tested under real driving conditions including racing sessions. This intricate process of research and development sets our headers apart from most cheaper headers which often fail to yield the expected performance and are often prone to heat cracking. So don’t save at the wrong end! Type: cast Flange: T25 top mount Wastegate: none / internal Type: for transverse engine On request we can deliver the manifold with a thread for measuring the exhaust temperature. additional charge: 35 &euro time of delivery: 1 week
