I was thinking and probably will order my headers for my civic. Are they direct bolt on where jus take the old ones out and new ones in ? Or are there special tools that i need ? Thanks

 

you might wanna get an impact air wrench incase you have some seriously rusty bolts ..... but a 12 and 14 mm is all you should need

 

its cake but like already stated sometimes those rusted bolts can be a bitch. i was one bolt away last time and stripped it had to cut the downpipe just to get it out.

 

cut the downpipe? why didnt you just take the downpipe off the cat.. and no one answered his question... there or nine bolts holding it on where it connects at the block and there are three where it connects at the down pipe.. Also all d series header should be interchangable same with b series engines... if you order them just order them for your car at a vehicle specific site then all you hvae to worry about is if they send you the wrongs ones, which can always be replaced..

 

i had everthing unbolted just one last bolt were the downpipe connect to the header and i ended up stripping it cuz it was so rusted even after i soaked it with pb. so i said screw it instead of fighting with it i might aswell cut it i dont need it. im talking about my old one. and its no hard to look under and figure out all the bolts you need to take out just look.

 

ok thanks everyone I was just making sure.

 

A torch will work wonders on an old rusty bolt. Flame it for like a minute and the bolt loosens like butter.
