High quality exhaust manifold by TurboWorks, made of 100% 304SS steel 3mm thick walls guarantee high strength and resistance to cracking Dimensions: Exhaust flange windows: 35x45mm Turbo flange: OEM twinscroll Inner diameter of pipes: 36mm A tight exhaust manifold is the basis of a smoothly running engine with turbocharger. When the serial manifold is cracked, the exhaust gas energy is not directed to the compressor. This results in a decrease in the power and dynamics of the vehicle, an increase in combustion, as well as increased noise emission and an increase in temperature in the engine compartment. It is then necessary to replace the collector. 24-month warranty. Additional accessories are also available for the exhaust manifolds: Lambda probe adapters Thermal tapes High-quality exhaust manifold by TurboWorks, made of 100% 304SS steel. 3mm thick walls guarantee high strength and resistance to cracking Dimensions: Exhaust flange windows: 35x45mm Turbo flange: OEM twinscroll Inner diameter of pipes: 36mm A leak-proof exhaust manifold is the basis of a well-functioning turbocharged engine. When the serial manifold is cracked, the exhaust gas energy is not directed to the compressor. This results in a decrease in power and dynamics of the vehicle, increased fuel consumption as well as increased noise emission and an increase in temperature in the engine compartment. It is then necessary to replace the manifold. 24 months warranty.
