Metal Catalyzer

Boost performance and enhance exhaust flow on your GR Supra with the HKS Metal Catalyzer Downpipe. Designed with a 150-cell high-flow sports cat (compared to the stock 600-cell), it cuts exhaust backpressure by 40% while remaining WLTC emissions-compliant.

Crafted from premium SUS304 stainless steel, it features a lost-wax cast outlet for optimal gas flow, delivering sharper turbo response and dyno-tested gains of +13PS throughout the rev range. The result is a deeper, more refined exhaust tone—89dB with the OEM muffler—without unwanted excess noise.

■Features

The HKS catalyzer has 150 cells compared to the stock catalyzer‘s 600　cells, resulting in a 40% lower exhaust pressure.
Gain an approx. 13PS advantage by just replacing catalyzer. (In-house test)
The outlet is made by lost wax casting in order to produce ideal layout.
The product satisfies the new emission regulations by selected a cell with an optimized ratio of catalytic precious metals.
WLTC emission tests are thoroughly conducted in-house, and a third-party test certificate is obtained.

Each HKS Metal Catalyzer includes:

• HKS Metal Catalyzer Downpipe assembly
• Gaskets and installation hardware
• Emissions compliance certificate
• Complete installation guide
