HKS Stainless Front Pipe
Stainless Front Pipe
Size : 75mm
2008-2014 IMPREZA WRX STI EJ25 SINGLE SCROLL
Reduction of secondary exhaust gas back pressure will improve response of turbocharger. EJ engines' common problem of knocking due to high exhaust gas pressure can be solved. Thus, it is recommended for safe performance upgrading.
•It was developed based on long time know-how of turbo technology.
•The connection portion with turbine is made by lost wax casting that enables flat surface between flange and pipe.
•Improved exhaust efficiency without catalytic converter. (Off-road use only)
•Whole front pipe will be changed from stock Φ60 to Φ75. It reduces secondary exhaust gas back pressure that is a common problem of EJ engines.
•For improvement of exhaust efficiency, diameter of the pipe is Φ75.
If it is used with the specified muffler (31008-BF001)(*), whole exhaust system will be Φ75.
* Front Pipe and Muffler system set (31008-BF002) is available. (This item can be used with other exhaust systems. A Flange Adaptor is included to fit to Φ65 spherical flange.)
