So this is the first time I've ever posted on any forum...Scary
I've read a lot of F150 forums and almost bought an Edge CS. Then I decided to google "Gryphon" that everyone was talking about and that introduced me to PHP. My girlfriend just gave me a $150 check so I could get the CTS. So, I just put an order in for a CTS. I didn't buy any custom tunes yet because I want to do the Gotts mod, replace my stock muffler with, probably, a Gibson(I don't want to go too loud but wanted a little more flow) and a little bigger tires this fall. I'm not sure if those mods would even change the custom mods but better safe than sorry.
P.S. Any ideas about a quietish exhaust with maximum performance are welcome. I'm a big hunter and I've noticed how loud exhaust scares the animals.
