Hello all, I have a 2012 ram 1500, just finished with most of my exterior work on it on now I want to start doing some performance upgrades. Since I don't know everything about my truck and most people probably know way more than me, I was looking for some suggestions. I have a moderate budget, I don't want to overspend but I want quality products. I'm thinking about a new exhaust for a more aggressive clean sounding exhaust with dual tail pipes coming out at 45 degrees on each side. I was also thinking about a tuner and how effective they can be but also I don't want screw up my truck with one. I also was thinking about a new air filter, cold air intake, or any other small upgrades if they are effective and safe to put on a truck, for example, i was told not to use a k&n air filter because it lets too much air in or something like that, not exactly sure, but any suggestions would be greatly appreciated
