Headers and H-pipe match up

Okay my Dad may be buying me some Long-tube headers for Xmas :D He knows he has to buy AOD specific ones, but here is my question I acquired a BBK short H-pipe w/cats that came off a 5-speed car a while back. If he bought me MAC Longtubes (they make AOD headers) Would it match up?

Thanks guys
 
I could be wrong and we need more people to chime in on this one, but I think it will work perfectly. It does not matter if it is BBK or Mac as long is it is Long tube to shorty with aod specific for both.

:nice:
