Selling Tomei Extreme Header for Nissan Silvia /180SX / 240SX with SR20DET Engine. (S13/S14/S15 model)
Our EXPREME exhaust manifold is now available for SR20 owners who
want a performance upgraded from the genuine exhaust manifold. With
our 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 our isometric prototype & the factory
genuine manifold which also utilizes the same layout, it shows that
ours has 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 our extensive
testing we have reached the conclusion that the normal design is
superior as a total overall efficiency. So to develop an exhaust
manifold similar with the design and setup as the factory manifold
we were finally able to produce a product worthy to bear our name
as a product that has the potential to deliver an overall increase
in performance.
