The genuine turbine outlet diameter is small which causes the secondary exhaust pressure to rise. This in turn results in a loss of power, response & unstable pressure. The TOMEI outlet has a larger internal diameter for the best optimization of exhaust flow efficiency & helps reduce the exhaust pressure substantially. The corrosion-resistant stainless steel material used in manufacturing this product is good with heat resistance up to the flange.
