?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 secondary exhaust pressure after turbine and primary exhaust pressure before turbine and improve the intake efficiency.

Use of this products lead to change of boost pressure characteristics. Use of this product with HKS muffler is possible, however use with other manufacturers products and use with altered boost settings may require knocking and maximum boost setting inspection. If necessary please repeat setting.
