I have a 1965 ragtop 289 w/single exhaust and want to convert to dual exhaust. What I need to know is what is the overall length of a stock 1965 mustang dual exhaust muffler. There are so many after market performance mufflers out there and I want to make sure I get one that will work with stock dual exhaust system.
Dual Exhaust Mufflers

Hmmm… Something else you need to know is the rear brake lines and hose need to be converted to the dual exhaust type, or the LH tailpipe will chafe the hose you have and disable your brakes.
As for the mufflers, why not just get ones made for the Mustang? You can get turbos or even Flowmasters that are sized and bracketed to attach using the stock hangers.

I can sure tell you what exhaust NOT to buy, lol. I got the dual exhaust kit from summit....what a pile of junk. You get what you pay for, its under my car now, looks and sounds good, but it cost some cash to get it that way, definately not a "bolt on" kit like it claims.
Muffler selection should be based on how loud you want it. You could get stock type mufflers, turbo mufflers for some good sound, or straight through for even more sound. I like Magnaflow, Dynomax, and glasspacks. Stay away from chambered mufflers like Flowmaster, because it resonates in the car way too much. I believe that 14 inch mufflers are what you need.
I recommend going to an exhaust shop over using universal or prefab kits. The exception to prefab kits are the direct OE style replacment kits. They fit well.
I agree about the rear brake line, that needs to be relocated.

If you are buying a kit you will probably have to modify anyways. Most of those are built around coupes and not verts. Verts are much tighter fit. I tried the aftermarket kit and it did not fit well. If you are going with cross pipe etc. I would recommend going to a shop.
those wont fit under a stang, but you can have it both ways with these and way more performance than those for less than half the price...........Dynomax Performance Exhaust | Mufflers | Dynomax VT Muffler
Motive kits, whether show-correct or modified, larger diameter, with turbo or Flowmaster muffler, are ALL made as the originals, to fit convertibles.
Oh, don't get me wrong, I still hate flowies. Last summer I think I drove a dozen Mustangs with them, and a five-mile test drive each convinced me more than ever I can't stand them. I have a car at home with straight-through 4" baffled mufflers (not glasspacks) and even they are better than flowies.
If you have seen or heard the Arvinode Mustang exhaust, I like that. Basically it's a tuned pipe instead of mufflers, with a small resonator in the tailpipes. If my GT duals weren't 'like new', I'd be looking into the Arvinode.
I have JBA headers, H pipe and flowmasters in my vert ,and im taking the flowmasters out. It sounds great at idle and wot. Its everything in between i cant stand. An i have sound deadner on the floors and the doors. I was going to add a resonator to eliminate the drone in the exhaust, but im just going to change the mufflers to the dynomax VT.

rsweld, a friend of mine with a '64 1/2 Hardtop 260 went from single exhaust to dual 2 years ago, using the Magnaflow kit. It has a beautiful sound to it. And it installed easily, snug to the bottom of the car. A quality product.
