These great looking headers gave every bit of the horsepower gains promised and also seen to make the truck run alot better. Great stuff!

These headers got installed on my 2003 f150 S-CAB but the install was easy but tedious and time consuming and the instructions are garbage. I recommend investing in a 3/8 ratchiting wrench you can buy them for around 10 bucks and also some high temp rvt silicone and also anti sieze. DO NOT USE SUPPLIED GASKETS! just use the silicone it comes in a red tube. Install passenger side first so you get an idea of how to do it take your time and finger tighten screws or use wrench but go slow and do not force screws in you will most likely cross thread good luck. oh and paint is crap starts peeling within 5 mind of heat exposure
