I have a 97 with the 2.5 liter and have had an exhaust leak for quite a while. When I bought it there was some gray pasty looking crap slathered on around where the manifold attaches to the exhaust pipe and it slowly disappeared so I figured that is where the leak is. I bought a new donut, at least that's what I always called them. I unbolted the flange and instead of just a piece of pipe to slide the donut on, there is a flanged piece of steel. I am unsure what I am supposed to do because obviously I can't add a donut to this. Am I going to have to do what was done before and use some exhaust repair paste?
