Turbo XS 02-07 WRX-STi High Flow Catted Downpipe

Introducing our latest design, featuring a high-flow catalytic converter enclosed in a robust cast 304 stainless steel bellmouth. The bellmouth seamlessly tapers to a 3" piping, ensuring optimal flow where it connects to the mid pipe. Unlike earlier iterations, this new Turbo XS Downpipe easily bolts to any stock or 3-inch aftermarket cat-back exhaust system.

DETAILS:

• 2-piece design
• The catalytic converter is removable without having to purchase a whole new downpipe (offroad purposes only)
• Cast 304 stainless steel bellmouth upper section for maximum exhaust gas flow
• 3.5" diameter 304 stainless steel pipe tapering smoothly to 3"
• Spare wideband oxygen sensor bung included
• Modified pipe path to provide more ground clearance for lowered cars than the previous design
• Hand TIG welded
• Polished to a show quality finish
• Includes new gaskets and hardware

NOTE:

• TUNE REQUIRED - Because aftermarket downpipes will change the power dynamic of your vehicle, a tune is mandatory to optimize the power and running condition of your vehicle
• Does not include the turbo flange gasket - It is highly recommended that you source a new gasket before the installation
