RE: 4.7 liter performance parts?
Don't laugh, but try changing over to a high quality synthetic motor oil.I've seen some shows that dyno'ed conventional motor oil and then drained and added ROYAL PURPLE synthetic oil. They ended up getting another 5 hp out of the motor. I'm pretty sure the show was Horsepower TV on Spike network. Personally I'd go with Amsoil.

I am a proud owner of a 2006 dodge ram 1500. I am looking for some opinions on performance exhaust systems for it. I would like to hear any suggestions.
