Next I slipped the muffler into the brackets to make sure it fit OK. Everything looked great! So I removed the muffler and stuck it into the trunk. I don't think it would be a good idea to drive the car with the muffler just hung from the brackets as it'll bounce around and could even fall off. The muffler can be removed without removing the brackets at this point, it just slips forward and out of the brackets.
I took the car to Midas and they did the rest. They ran a 2-1/2" pipe from the front of the muffler over the axle and up to the left headpipe. They cut into the headpipe and welded the new pipe to the opening. They had to remove the existing harmonic balancer off of the right pipe. I've driven it about 50 miles and have not noticed any new vibration (it has always had a little vibration right at 2100 RPM, it's still there but not worse).
That's it! Mainly I did this for looks, I really didn't like the single exhaust. This is a Mustang after all! It NEEDS duals, even if it is "just" a 6

It sounds much better than stock, it has a nice, deep V8 sound to it. It's definitely not as loud and throaty as a GT with an aftermarket exhaust, but it sounds very good
