I recently registered after viewing and reading threads on this site for a year or two.
I have the opportunity to get a b series swap but I am not really sure about exhaust fitment.
1. will any of the b series stock manifolds or aftermarket headers fit a d series stock or catback exhaust?
2. will any of the b series full exhaust fit ?
3. will a adjustable test pipe solve any fitment problems with a d series catback to the b series motors(ive read conflicting posts on this)

I just cant seem to find solid answers other than get a custom exhaust from a shop. Alot of writeups I have read completely left out anything about the exhaust.
