Hi, i'm new to the forum and i have a few questions about my truck. I have an 04 supercrew 5.4L and i was wandering what would be a good programmer for it and what exuast system would make it sound deeper and a little louder.

 

Do a search and you'll find hundreds of posts on programmers and exhaust. IMO SCT x3 or the Gryphon CS/CST for the programmer and Borla, Magnaflow, or Dynomax bullet are all good muffler options.
