could i use the headers off an F150 4.2 litre on my 3.8 2002
i may have cracked my passenger side header and i founda 4.2 i can get theheaders off of for cheap and im getting my exhaust donelike next week so ill do itall at once

 

They won't match up to your mid pipe.

 

im getting a new mid pipe (off a mach 1/GT/Cobra/4.6)so i should be ok right? im now doing exhaust headers back. how much do you think a u pull it will charge for the cats and headers off a 4.2L?

 

You should use 3.8L headers and an aftermarketV6 Mid pipe. Shouldn't cost too much.

 

what would be the problem?

 

will the headers bolt into the head? im getting all new custom exhaust done. will it point a completely different direction?
