Upgrading my 2008 F450

Hey guys. I have a 2008 F450 King Ranch. It currently is stock, only with a cold air intake. I'm looking to improve the performance by upgrading the exhaust n throwing in a programmer. Any ideas or reccomendations to which products or any additional ideas to throw in my truck? Thanks for time. -Rick

I have the 08 450 and put the SCT Livewire on it and deleted the cat and DPF. Have not towed much with it and had a hard time figuring out the SCT Livewire instructions. Called the office but not much help there either. Wanted to know what the tranny changes mean. They told me to just experiment!!! Well, that takes a lot of programing and reprograming so just using Extreme tune for running around. I did not get that much increase in mileage. Probably from 10-11 before to 12-14 max. I try to keep the RPM under 2500 but with 4.88 gears that seems slow on a long trip! Would like to do the LED tail lights but need recommendations on that and wonder how much the COLD AiR intake did for you? I thought Fords was pretty good as stock?!
