I still have a d16y7 and was wondering how to take off my stock headers and put the megans on.

*headER*


piece of cake

its just a few bolts, real easy job

take off the heat shield, then the nine 12mm bolts that hold it to the head. next get under the car and take off the two spring bolts that hold it to the cat. you will need a 12 and a 14 to do that. disconnect the o2 sensor and take the whole manifold out. you will need a 7/8" wrench to get it off. i not sure where the o2 bung is on the megan header, but you might have to extend the harness if it is close to the cat, if not, dont worry about it. then reverse the process. you will prob need some plyers to compress the exhaust flex springs and a new exhaust mani gasket. all in all its really easy

^^^^ well put.
