The Japspeed Stainless Steel Sports Cat Downpipe is designed to improve exhaust flow and turbocharger performance on Subaru Impreza GC8 Classic WRX and STI models from 1995 to 2001.
Replacing the restrictive factory downpipe and catalytic converter with a larger 3-inch stainless steel downpipe allows exhaust gases to flow more efficiently, helping reduce back pressure, improve turbocharger response and support increased engine power output.
Manufactured from high-quality T304 stainless steel, this one-piece downpipe incorporates a 200CPI sports catalytic converter, designed to improve exhaust flow compared with the original catalytic converter while retaining a catalytic element.
The downpipe features TIG-welded construction and CNC-machined flanges for strength, durability and secure fitment.
Designed as a replacement for the factory downpipe and catalytic converter assembly, making it suitable for performance-focused Subaru Impreza applications.
