So I'm in the process of revamping my exhaust. I've taken the ASV brackets off of the exhaust manifold, and I'm going to extend my Y-pipes up to the engine itself without the brackets. I took the old crusty gaskets out, and I'm buying new ones. But all of the gaskets that it seems I can order are just simple rings, whereas the ones that I took off were the shape of the pipe flanges on my Y-pipes. My engine is an EA81 on my '83 BRAT. What kind of gaskets do you guys have at this spot? Will the simple, circular ones work? My whole point of working on the exhaust in the first place was to keep it from leaking right at this spot, so I want something that will hold well.
