High-quality exhaust manifold by TurboWorks, made of 100% 304SS, 3mm thick walls guarantee high strength and resistance to cracking. A sealed 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 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 manifold Fits: Audi A3, A4, A6, S3, TT Skoda Octavia Seat Ibiza, Leon VW Bora, Golf, Jetta, Passat Flange for mounting T3 turbines Wastegate output with a diameter of 38mm for 2 bolts or V-BAND Exhaust windows in the flange: fi 41mm 24 months 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.
