I have a used CA header and downpipe w/ cat with only a header gasket. The dealer just installed a new cat yesterday because the flex pipe blew a hole. Can I reuse the stock dp gasket that they just put on? The 2 gaskets they used were 15235773 and 15231157. A search on the internet didnt tell me what gasket went to what part #.


edit: how many gaskets do I need total? 3 right or is it just 2 the header/block connection and downpipe/header connection

 

anybody?

 

You should be able to use those gaskets if they are not already burnt up. The rear gasket where the downpipe meets the cat-back is easy to get ahold of at any parts store. The manifold to downpipe gasket is a lot harder to find.
