I am installing my 2.5" Catless down pipes and wondering what exhaust donut I can get to bridge the gap on the manifold to downpipes area.....I read one guy used 2.5 outside diameter and 2.25 inside....not sure where I can get those from beside local auto shop....thanks in advance!

Anyone? I went to oreillys tonight and couldn't find what I needed. Thinking about going to an exhaust shop and seeing if they will sell me a donut

I don't know the answer...but it could be because you posted in the new owner forum rather than technical.

Not sure what down pipes you have, but the stock ones don't use any gasket between the exhaust manifold and down pipe.

It wouldn't let me for some reason
