1967 Hipo Exhaust Manifolds

Can anyone tell me the difference in the 67 hipo exhaust manifolds from those of the 65-66 manifolds? Also, do they have a different h-pipe? I have a set of 67 manifolds that I want to put on a 67 GTA, is there a 67 h-pipe or can I use any hipo h-pipe indifferent to the year? Thanhs guys. Tim

67 manifolds are clearanced for thermactor tubes even though most 67 Hipos did not have the system. The 67 uses a C7ZZ 5246 H pipe and I believe that the pipes are longer than the early Kars however there may be some other difference.

Also the '67 kars are wider and they took advantage of that as well.
