I'm about .02 seconds from pulling the trigger on a set of OBX headers. Aside from going with a new OEM gasket, what else would be a wise purchase right now? I can think of a couple things but I would love your input as well.
1. OEM gaskets
2. plug wire sleeves
3. new o2 sensors while I'm down there (pushing 84k miles)
4. ARP header fasteners
5. Provisions to bolt up to a Corsa
6. additional heat protection for other stuff?
If you have not removed your stock cats lately lay in some spray cans of Liquid Wrench or PB Blaster. Saturate the cat-to-exhaust manifold nuts and bolts several times (hours apart) before the disassembly. (1/2 inch air impact wrench or breaker bar).
I already have new mounts but I may have a single RC51 mount up for sale after I do this. I'm thinking about swappin mine out for another UUC like I have on the passenger side. Right now I have a little more vibes than I would like...
You are on track especially with the ARP hardware for a single man DIY. This way you can "hang" the headers on the studs from underneath. Of course if you have a hand around they are still good to. BTW I didn't use any cool sox and have been problem free for over 15k but did some zip tie work around them.
