Invidia offers both catted and catless downpipes for the 2010-2012 Legacy GT that are designed to free up exhaust flow for better spool times and more power. Every Invidia LGT downpipe features 3 inch diameter stainless steel piping for maximum flow and 1/2″ thick flanges for added strength. This is easily the best bang for your buck modification you can do to your Legacy GT and will not disappoint. Please note that without engine management, a catless downpipe will trigger a check engine light.
Engine management for the 2010-2012 Legacy GT is very sensitive towards exhaust changes. An Accessport is recommended to tune the car appropriately to prevent Check Engine Lights.
