Tomei's EXPREME exhaust manifold is now available for SR20 owners who want a performance upgrade from the genuine exhaust manifold. With their product, you can retain the genuine setup and no special modifications are needed to fit the standard turbo. With the SR20DET the exhaust manifold was designed to be close from the exhaust port to the turbine. With the comparison test of their isometric prototype & the factory genuine manifold which also utilizes the same layout, it shows that their's have succeeded in delivering an overall improved performance in both torque and power increase in areas like in the higher RPM range in which you were not able to utilize before. With their extensive testing, we have reached the conclusion that the normal design is superior in total overall efficiency. So to develop an exhaust manifold similar to the design and setup of the factory manifold they were finally able to produce a product worthy to bear their name as a product that has the potential to deliver an overall increase in performance.
