I have a 2005 legacy 2.5i AT, non turbo. I found an aftermarket exhaust manifold for the car, but one of the notes say; you can use the stock downpipe or an aftermarket downpipes that fits. The brand is Tsudo, if anybody has ever heard of them. Are there any sensors in the stock downpipe? Should I change the downpipe? Thanks
