ITEM: HKS METAL CATALYZER for SUBARU Legacy (Liberty) Wagon BP5 (EJ20Y/EJ20X) 5/06-

The Metal Catalyzer that has both high output and high purification system.
Legacy B4/Legacy Touring Wagon/New for CBA-BL5, BP5

Features

• The combined Front Pipe catalyzer for D, E (CBA-)BL5/BP5 that the exhaust gas regulation area is changed and got much strict.
• With the reduction of Exhaust pressure we still have passed regulation and received public organization's exhaust gas test certificate.
• HKS product could reduce the exhaust pressure 300 cell + 150 cell, for the stock has about 900 cell + 400 to 600 cell.
• 300 cell catalyzer is newly developed that has lowered resistance to close to 150 cell type.
• We set the bypass pipe at the extension part from turbine to prevent disturbed flow of the exhaust gas and the joint part of muffler is originalφ65 Spherical surface gasket and we have widened pipe diameter.
• These will prevent knocking of EJ20 tuning that is a weak point because of high exhaust pressure 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.
