The Metal Catalyzer that has both high output and high purification system.

■Features

• Metal Catalyzer for both MT and AT.
• 150 cell catalyzer is used for both exhaust efficiency and durability.
• High efficiency gives 5 to 7ps up. The choked feeling is also improved.
• It's designed for supercharger spec power up, therefore you don't have to worry about the NA, turbo or supercharger for installation.

* When you install the Metal Catalyzer, the exhaust sound tends to get bigger. Please be careful for Z33 that could have 3 to 4dB higher depending on the type of muffler or the time-related deterioration.
