Thank you for finally giving me the answer I was looking for. That is what I was afraid of. I may try to have it welded like cgpEJ6 suggested. I tried something called ThermoSteel and that worked for a short time but it finally burned off.if you just want a new manifold because your current one has the crack in it you're going to need to buy a new mani-cat assembly. the second picture looks like it comes apart, but its an aftermarket piece. from the honda factory the cat and the manifold are not separable. the two picture you posted are not the same things even, pic 1 is NOT the top half of pic 2.
Thanks for the offer but it looks like that won't work for me. My car has 169,XXX miles so dealer help would be out of the question anyway.nevermind your cat is not bad.
they can be seperated. All you need is the upper manifold. I might even have one for you. Pay shipping and you can have it. Ill just have to check if I have it. PM me if youde like
