2007 Forester XT
Today I made contact with an individual who is returning his 2008 WRX to stock, and I am hoping to upgrade my 2007 Forester XT. He has Turbo XS catless downpipe, and I have stock downpipe. I'd take his Turbo XS off the WRX, and he'd get my stock DP. I know I can take his, can he take mine to complete the swap?
