ok, here goes...
I'm not sure what they are called, I think they have something to do with the EGR system. I'm wondering what the 2 things are on the exhaust manifolds??(1988 305 tpi) Mine are both broken up top, the little tubes all meet up to a collector, then theres a nut and i believe some kind of valve. They are both busted right where the "collector" meets the valve. I just want to know what they are called so I can replace them, but no one around here can help me out.
I found a good picture of this on eBay, i don't know if i can put pics up here, but heres the link to the picture

forgot to add, if you look at the pic in the link, its right where the gold meets the black thing on top, was wondering what both these items are?

 

One way AIR check valve. Keeps exhaust gases from going back into the AIR pump. Available from any parts store. Racers use them on header evac systems for the same reasons.

The tubes themselves are exhaust AIR injection tubes for the manifold.

 

dude dont buy that crap... ur better off gettin headers on it and getting ridd of all you AIR injection junk its hard to work around all the hoses and they look like ****. where are you from if ur heart is set on keepin that stuff i'll give u mine real cheap.

 

Just buy a set of headers with all the AIR attached if you need emission controls. forget that e-bay junk, its just that junk.

 

thanks for all the help. I know i should get headers, i just dont have the tools to get them on...yet at least

 

ur going to need the same tools to put the stock manfolds on/off

 

all i used to get my headers on was a few sockets man... get sum deepwells. if u gotta saw, dremel or sumthin u can cut your exaust with your set. everything after that is the exaust shops job
