Pre-catalyst is a front pipe front pipe for the purpose of response up original turbine to reduce the secondary exhaust pressure of the turbine exhaust achieve ideal efficiency of the exhaust flow smoothly to remove the catalyst structure. Through the use of stainless steel, oriented! Flange also use stainless steel for durability, it has reduced the exhaust resistance of the flange portion.

※ Full 80φ adopted, significantly reduce exhaust resistance.
