Headers stuff
no real differences from them at all, just mainly how they are made and what they are made of. the QTP ones are gonna last b/c they wont rust like pacesetters which will rust over time but not all the way through just they wont look like new in acouple of years like the QTP ones will. and the pacesetters fit alot better than those other ones also so that is another plus about pacesetters.
not really if there is it isnt much at all, pacesetters are good headers especially for the price. you could save yourself money and get more mods for your car instead of wasting that much money on headers, i just got my pacesetters the other day and they are great looking headersk, just dont get the pacesetter Y pipe instead buy the TSP 3" offroad Y it is much better flowing.
