Features

• A Metal Catalyzer to give more to the Legacy tuning. It's a combined unit type of Front Pipe with 150 cell catalyzer.
• There are for both 5MT and 4AT. We have received public organization's certificate of 10-15 mode exhaust gas test for both.
• We have set bypass pipe for extension part to prevent the exhaust gas turbulence and also we have redesigned spherical surface gasket and increased pipe diameter for muffler connection part.
• These will prevent knocking of EJ20 tuning and lower the secondaryexhaust pressure after turbine and primary exhaust pressure before turbine and improve the intake efficiency.
