This stainless steel cat-back exhaust system is designed to improve exhaust flow, engine performance and exhaust sound on the Subaru Impreza WRX STI (2001–2007).
Manufactured from high-quality T304 stainless steel, the system features a 3" bore and a 4.5" tailpipe, providing a larger and less restrictive exhaust path compared to the standard factory system.
Replacing the restrictive OEM exhaust with a freer-flowing cat-back system can help improve exhaust gas flow and engine responsiveness, while producing a sportier exhaust note.
The three-piece design features TIG-welded construction and CNC-machined flanges for strength, durability and accurate fitment. All necessary gaskets and bolts are included for installation.
