I hope not, since that's what I have for my '79...

Darrell at Techtonics recommends sticking with the 2" exhaust for most 8V
engines including 2.0L's with a mild cam.
Unless you have a ported and polished head with a radical cam, it's not
worth it to go with the 2 1/4".

As long as it has the straighthru muffler, 2" is plenty for an 8V.
