exhaust question...

okay i have a 98 civic and i was wondering, is it possible to get a cat back right now for the d series engine and later down the road when i get a b18 swap, possible to use the same exhaust? would it matter because of the different engines? i was thinking of getting the hks hiper or the apex n1.

you should be able to find any competent muffler shop able to modify the exhaust to fit the new motor once you get it.

You shouldnt have to modify anything. it should bolt right up unless you get a motor with Jap headers.
