i'm new here and looked up this question but couldnt find the answer i was looking for. i'm not very mechanical,so i have friends at a shop put my mods on for me,i pay them of course,but when i ask questions about this kind of stuff they try to talk me out of it,so its easier to ask here,get what i need,and then just give it to them to put on.after all,they arent stupid,i do pay them...lol...anyway, i have a 2012- 1500,i already have the customary new truck starter bolt ons,K&N cai,air raid throttle body,flowmaster 40 exaust.i know alot of guys put the magnaflow on for better performance,and if i need to in the summer maybe i'll switch to them.for now, the truck sounds fast if anything. i was debating on adding headers and wasnt sure what i needed,shorty's or long tube. i live in ny,so i'm really not looking for anything top end,there arent any tracks here anymore so i cant really open it up too often legally,75-100mph can get me in alot of trouble.so i'm looking for a little more boost off the line.i'm also open to doing more motor work in the future,a little at a time,as the top quality parts are expensive,so i was wondering if the headers were a good step in that direction,& would i notice the difference? and what would possibly be the next step afterwards with what i already have. thanks for any input.
