Which exhaust is better

Id go shorties. Tell you why. Tire clearance, and tub compromise. EDIT; Id go shorties if you can find some.
-I put a 340 in a 65 valiant wagon back in about 74.At that time Hookers were the only header choice. The factory 13 inchers would work. But no serious rubber would fit in there and not rub on turns.
-The tub compromise, I guess only arises if you butcher the aprons, which is somewhat easy to do. If you are going to cage it, well new story.

66340; that there is a sweet install. Man,I almost forgot how tight that bay was.Nice work.
