A strong SUS304 stainless steel is used against corrosion. In addition, taken up slightly bigger (φ45 ellipse) the opening of the flange,

The exhaust efficiency is improved, also in the pipe diameter, by which the optimum size of several to SR16 engine and suppressing torque loss of the low speed range further.

The equal length 4-2-1.

By adopting a set of methods, it is reducing the exhaust resistance.

It is one article in pursuit of the ideal exhaust efficiency at high rpm until smooth
