Primary j-pipe for 2022+ WRX - OEM fitment replaces the stock primary cat with a high-flow GESI 400 catted j-pipe optimized for maximum flow and quick spool within the confines of the stock catalyst pipe. This component requires a tune.

Lead times may vary, but 1-3wks is expected, depending on order volume. This product in particular may see extended wait times as GESI cats regularly are out of stock. If you have any concerns, feel free to message me here, or on IG @wopsy.autofabworx!
