The factory 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. If used in conjunction with the TOMEI ARMS turbine. You will see large gains in all aspects of performance. The corrosion-resistant stainless steel material used in manufacturing this product is good with heat resistance up to the flange.
As seen in SAMMIT‘s videos the gains of adding this to your skyline before a tune are huge! In his case he saw an increase of up to 70HP from just adding it alone!
