Okay, so I bought the Oil Dipstick from Paul, Header Gaskets from Jerry, Stage 8 bolts from Summit Racing, going to buy high temp copper Permatex from Autozone tomorrow....Now it is New OBX for $550 or used Watson headers for $700.

I have to find out which cats to buy and get them fabricated to slip one end on my 2.5 inch Corsa exhaust.

The last thing is whether or not i need an O2 extension and where to buy them. I bought new O2 sensors and see the 3 prong clip.

Do i defnitely need an extension and where would I find one for our cars?
