WEDS REV CATALYZER FOR SUBARU IMPREZA STI E F G GDB RCL-S005

Best advantages of the WEDS Rev Catalyzer (RCL-S005) for Subaru Impreza STI (GDB, EJ20 6MT)

• Lower back-pressure / better flow — uses large, low-resistance cells (about 200 cpsi vs ~400 cpsi on a stock unit), so exhaust flow is much freer which helps power and throttle response.  
• Higher power & quicker response — the reduced pressure loss and larger cell diameter are advertised to produce noticeable gains in mid/high RPM power and quicker engine response vs the stock catalyst.  
• Street-legal / inspection compatible — Weds markets the RevCatalyzer as meeting vehicle-inspection / safety standards (so it keeps you within emissions/regulatory limits while improving flow).  
• High purification performance (precious-metal coated) — despite the lower cell density, the honeycomb is metal-coated with precious metals to maintain strong catalytic conversion / emissions control.  
• Durable stainless construction — made from SUS304 stainless steel for good heat resistance and corrosion resistance (longer life under turbo/high-temp use).  
• OEM-fit / bolt-on for specific GDB variants — designed and sold specifically for the GH-GDB (applied codes E/F/G) 6MT models — easier install and correct fitment.  
• Aftermarket availability / known pricing range — sold through Japanese performance parts sellers and marketplaces (expect OEM-quality pricing; used/new listings appear on sites like eBay and Japanese shops).
