Hello, I am putting a brand new exhaust on my 1998 Forester and think that the original is what I am taking off. So being as I live in MN the heat shields are rusty and if I get them off the old exhaust I am certain they are destined for the junkyard. So can I wrap my new exhaust from the headers back to the rear cat and call it good? I would like to hear anyone's (with a few exceptions) opions on how to go about this and what parts and products they would recomend. Thanks for your time.
