Here are photos from Pypes website, it looks like you'll have to cut the ends off if you want to use the factory style tips.
Just wanted to let you all know, that that is my Dart on the link. I had just installed TTI's and called them about their systems. I'm about 45 minutes from their shop. They had never installed, nor had a customer, their tailpipes on an A body so we worked out a deal for them to install a complete system from the collectors back. Went w/the 2.5", x pipe, street pro muffs, and the turn down tails. They installed it all in their shop w/myself present. The TTI collectors were not used as they hung too low to mate up to the x-pipe. They fabricated the collectors there to get them closer to the trans x-member. All in all, everything fit nicely and I'm very pleased with the sound. Barely any drone and comes in nicely @2.3k rpm and up w/a mild 360.
Regarding the turn downs. At the time, that's all they had so I rolled the dice until I was ready to install the tips. Due to the bend in the tails aft of the tank, there was no way I could use the correct Acccurate 2.5" tips for a 69. They would have stuck out several inches from the bumper. I chatted w/Accurate and they suggested to go w/the 70 style tips as they are shorter than the 69's. Of course the L bracket didn't line up w/the hangar. Had to mount the hangar bracket to the rear panel under the bumper. I simply cut the turn downs off and left enough to slip in the tips and used band clamps to snug them up.
Again, I got a real good deal on the entire system and pleased w/their product. I called them back regarding the tip installation so don't know if they corrected it or not.
