Finally put the 5" exhaust tips on. They were shiny stainless that had been painted by the guy I bought them from. They were stripped and powder coated black by a friend, and finally got time and enough moral support from my wife's cousin to put them on. I will probably have them welded on; they are held on by 2 clamps on each side now.
I also installed the Hellwig anti-sway bar after the rear spacers were put on. I think I'll set it at the firmest setting. I like it now, but think it's not terribly different than the stock ride using the middle setting.
Now my list looks like this: (in chronological order)
Already done are:
1. Magnaflow muffler swap
2. Tinted side windows for driver and passenger to match factory rear
3. Stubby antenna
4. DeeZee slow open tailgate mod
5. Ram lighted hitch cover with hurt pigtail wiring
6. LED reverse lights
7. Factory Ram molded mud guards.
8. Weathertech floor mats front and rear
9. Undercover ultraflex tonneau
10. Swap front grille inserts from shiny billet to black honeycomb (like the Express version)
11. Level with Bilstein 5100s up front
12. TGC 1.5" rear coil spacer
13. Hellwig rear Anti-sway
