Hey guys, I'm looking for some suggestions on adding some hp's for my 2005 4.7 V8 ram. I have already installed flowmaster dual exhaust with no cat convertor and I have been contemplating adding cold air kit, superchips, throttle body spacer, headers, and 212cam only if it does not affect my warranty. I was wondering by adding all these upgrades would I really notice a differance or am I'm just playing catchup with the Hemi. Also is there a lift kit to level out my truck? Thanks for all your help!!!
