PART NUMBER : 33005-AT012
HKS METAL CATALYZER GR YARIS GEN 2 ( 33005-AT012 )
■Features
- Compared to the genuine fine-cell ceramic catalyzer, this product utilizes a low-density metal catalyst. Both the primary and secondary catalyzer adopt a 150-cell design, significantly reducing exhaust resistance.
- The primary catalyzer features a compact cell structure with an optimized ratio of precious metals, achieving both effective emission purification and reduced exhaust back pressure. This design meets regulatory standards and has obtained an official emissions certification.
- To protect against heat damage, the primary catalyzer is designed to allow installation of the genuine heat shield. ※
- While the stock pipe diameter is 70mm, this product increases it to 75mm to further enhance exhaust flow.
- The surface is buff-polished, and all welds are TIG-welded for a premium finish.
- Includes dedicated brackets for both MT and AT models.
