On my GSR, it was a pain since they were a 4-1 and I couldn't get them in without unbolting the slave cylinder. It all just depends on how mechanically inclined you are. It isn't really hard once you get the bolts off the old one. Check out www.c-speedracing.com for a how to and see if you want to. I don't know the specifics of putting it in your model but it is pretty universal.

And by the way...it is header not headers. There is only one.
