74 Formula 400 exhaust tips
Hi All,
I have bought 74 exhaust tip repro's and would like to know dimensions for placement. How far should the pipes be from outer edge of the body and how far from the bumper bottom edge. Trying for the factory look. Thanks in advance. Cheers, Pete. |

I believe that the pipes and mufflers didn't change from 1973 - the only change was the tips;
I would tuck them up further than this picture if I was you (and it is possible).

Thanks Guys, I appreciate the feedback and pictures. I've looked at a lot of pics of 74/75 birds with these pipes with different variations of angle and clearance.
I have a crossflow muffler with 2" pipe to the exhaust tips which are 2" inlet/2.5" outlet and wondering the best way of connecting them is just clamps or ? The car came with just 2" steel tailpipes that have a bracket connected to a rubber hanger, looks factory. Thanks, Pete |

Here are some picures I save while researching the the exhaust for my car. Looks like they are clamped on.
