exhaust change -first gen motor in a second gen

[curbjibn]

If you are putting a first gen motor in a second gen eclipse. Do you get a exhaust for the first gen or the second gen? Or does it matter?

Which part of the exhaust? The cat-back, downpipe, exhaust manifold, blow off valve?

Most if not all the parts would be for a 2g because of the body, and undercarriage. Some internals may need to be 1g parts because of the 1g engine. Not sure on that though.
