How hard it is to install headers on 5th gen?

I can have a good deal on Hotshot headers but im worried about the installation... What kind of mechanic experience you need? Does anyone have a good how-to ?

thanks

its not hard to do, expecially on a relatively new car, where the bolts aren't rusted on. the hard part lies in unbolting the thing without a lift. Because you ill probably have to get under the car at some point to unbold the stock pipe, and, using only a jack, you have limited room, and its dangerous...

But as far as ease of installation, its just unbolting, and bolting... and don't forget gaskets!

is it common to see trouble with SES light ? What about the o2 sensors? Does everything fit right in its place?
