Yea man it's all bolts off and on again, it's recomended to switch out the manifold gasket for the new one that came with your header, but all mines came with those cheap ebay one' that felt more like paper so I just went and bought a new oem one to switch it out with. You would only need basic tools for this and make sure to disconnect the sensors when you get underneath the car there.

is it for a gsr? when i put a header on my single cam the O2 sensor was seized into the stock header so I had to buy a new O2 sensor. also, be careful as when I was torquing the bolts that go into the head one of them broke. took about 30 mins to do since i still havent drilled out the broken stud. also, most of the cardboard composite gaskets that headers come with a POS, so go get an OEM/metal gasket. the ones from autozone seem to work just fine.

First thing, is the header you bought for a 98? That will make a big difference in fittament. If all you need is a o2 sensor bung you could take it to a muffler shop and have one put it (provided that everything lines up). The bungs cost around $2-3 and a shop will drill your manifold and weld for under $15. I suspect you might have the wrong header.

bseries is easy! Try k series esp. the new si! i had to drop the subframe go at it from the top the bottom this side that side. heat wrap this wire, bend this sheild. oh yea and to get at it from the top u gotta take the cowl cover and sheild off. also getting a torque wrench up there was mad fun!

what exhaust are you running? i'm having a hard time finding an aftermarket header that will bolt onto a 60mm (about 2.3 inches) exhaust without any bottlenecking. most headers have a 2.5" outlet.
