Headers

Hey im gettin The Other Guys Headers from doctorspeed.com and it says they have to be welded, so i was wondering how long that takes cuz im trying to figure out how much its gonna cost at the shop for them to install them`

The downpipe must be welded to the cat during installation. A good welder can do this in about 10 minutes, I assume you will need to cut the old pipe off so allow 30 minutes total. Should cost you less than $20 to have it done.
I suggest that you fit everything up and mark it, then take it to a welding shop and have it welded. If you would rather install it and then take it to the shop that is ok too but you may have trouble connecting the cat to the downpipe to get it there. Good Luck!!
