High efficiency 4-1 type adopting Genuine products 4-2-1 type is not excellent in exhaust efficiency because it narrows down immediately to 4-2. However, in our products, adopting the 4-1 type which excels in exhaust efficiency increases the turbine response and the turbine exercise rate, and the driving feeling changes drastically.
? Unequal length design Although exhaust interference is eliminated at perfect equal length, due to the structure of the vehicle, the turbine response decreases due to the distance to the collecting portion becoming longer, the structure becomes complicated, There is a tendency to increase. In case of unequal length, you can aim at the effect of pulling the exhaust of other cylinders by using exhaust interference in reverse. Our products comprehensively considered those points and adopted unequal length from repeated test data.
? Support pipe diameter large width enlargement Genuine product ?42.7 ? made by TOMEI thicker It is improving the output in the high rotation range by thickening it. If this support pipe diameter is used, excellent performance will be demonstrated at boost-up and turbine change. Fits on all EJ20/25T!
