tarmon ...I run a TRZ suspension (all rear components mentioned in previous post). I did the install... wasn't too bad really. You need a mig, a buble level, a tape measure, etc. etc.
Any rollbar that mounts to the framerails and has roller bearings is a good setup IMHO... HPM, Wolfe Racecraft, to name a couple. The TRZ anti-roll bar I use attaches to the floor pan and works pretty good so far.
As for exhaust... I do not run tailpipes and I'm not sure what anti-roll bar allows for 3" tp's if any even do. I'm going to run open headers next time I go to the dragstrip. I run the time in my sig through 2 1/2" Magnaflow mufflers with turn downs... gonna see what kinda difference it makes.
I recommend you do more internet research and what not to learn more about them, see some good pics of different brands and do a search on every major mustang forum on the 'net to see what you come up with for good/bad product reviews.
Good Luck!
red I hear ya! Once I finally made the move from street tires to slicks at the strip, I wondered why I even wasted my time on regular radial tires
