Installing Momentum Headers

AlexRaymond19

I can grab a pick tomorrow, but you are right, it is solid metal... You have to attack it from under where the metal stops, with the wheel off. It was the only way i could see to get the 2 bolts under the header in the back off. Those are actually the easiest to get off! I used like a 24" or 36'' extension with a 3/8's u joint at the end and a deep socket 14mm. It helps to have a helping hand reach in to the headers and grab the socket and place it on the bolt because it is too floppy with the u joint on. IF you don't have someone to help you, take some wax or really thick grease and put it on the u joint to make it more rigid so you can align it. (picked that trick up in the AF from a F-16 crew chief) Luckily I got the last one off right as my U joint broke, so you might want to have 2 available just in case. Really the only other thing that has stopped me in my tracks for a while was the O2 sensor on the header. You cant get to it with a wrench while the header is on, so you have to unplug it from the harness... Which sounds easy, but its located in such a spot where it is damn near impossible... Luckily i have a pair of super long needle nose pliers. It helps to snap the plugs off of their mount, that frees up a few more inches of wire to work with
