TTI exhaust

I'm a TTI dealer and have 3 of their systems on my Dart. Currently, I have a 3" H pipe, 18" 3" mufflers and 2.5" tails blown up by TTI to fit into the 3" muffler. I like the H pipe as it fits with my Metco one piece driveshaft safety loop. The X pip does not allow this. Both H and H pipes could be tucked tighter to the floor pan, but that's my only minor complaint. On the whole, their systems fit great. If you have a 4 speed, spend the extra to get their modified Z bar, I did.
