Exhaust pipe part number question 3863497/3863498

[Brad M.]

I was wondering what years /applications that the part numbers 3863497 and 3863498 are correct for regarding mid pipes. These are 2.5 inch.

I have a used set of these that I was told came from a 68 small block car.

I also have a NOS set which I bought from a guy who said they came with a mid-year that he bought.

I have a 68 AIM, but the part numbers in it do not seem to correspond, I assume this is bacause the factory part was an assembly with the mufflers and probably carried a different part number as a result.

Anyway, are these correct for 68 or for mid-year or possibly both?

Hi Brad
They fit 63 S/B 64 S/B 65 B/B 66 and 67 B/B These are probably the squared type pipes in the mid section, Not for 68's. BTW I haven't decided on the mufflers yet. Might still get a one piece welded to them, however I'm still looking for a 68 N11 one piece off road muffler system and I also need the front pipes 3880401 and 3869584
Thanks, Grant

Thanks Grant, they are definitely more squared than the '1830 and '1829. The front pipes that I have are for small block, that is basically why I got them to get another set of the pipes that go from 2 to 2.5.
