Dual exhaust for my 273, 2, 2 1/4 or 2.5

[Torkmnstr]

So I am trying to decide what to run. It has a 2" single on there right now. The motor has been rebuilt to a little over factory some years ago. Not sure what all has been done(second owner and all). But I want to open it up some drone the manifolds, with that said what should I run. I am leaning toward the 2.5" but I'm not sure if that's a bit overkill for my setup. Thanks for the input all.

2 1/4 gets my vote. I would fit in a x pipe too. To do it correctly you will need to modify the transmission crossmember because it is only designed for a single system. I put the original styled single system on my 66 made by Accurate LTD. It fits well, works well and sounds good. A little spendy though. tmm http://www.accurateltd.com/1965-67-273-Hi-po-System-for-Barracuda-Dart_c_69.html

2" is much more than sufficient. 2.25 I would say for bragging rights or bench racin.

I've got dual TTI 2.5" system on my 65 Formula S (318 with the original Carter AFB). Obviously, this is overkill for now, but at least it's ready for more radical modifications in the future.

Yea think the price will decide for me. I will quote it for the 2 and 2.25. If there is not much between the two then I would prob go for the 2.25 for possible future upgrades. So that crossmember doesn't have dual humps for that eh...

Nope. You can modify it or send it to Cosig and he will do it. There are other threads here on the subject. tmm

Hmm I will have to crawl under and take a look, mine is a 68 though so maybe they started doing them by then for the hipo cars...

So I'm good, we have dual cutouts.
