A Metal Catalyzer to give more to the Legacy tuning. It's a combined unit type of Front Pipe with 150 cell catalyzer. 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 secondary exhaust pressure after turbine and primary exhaust pressure before turbine and improve the intake efficiency.
