Hey guys!

Im visiting the US right now, so Im picking up a few little things for my cars.
Im going to remove the Smog stuff off the IROC, so I need to buy an end cap to plug up the smog tubes from my edelbrock TES headers. So, what I need to know is the size of that thick pipe - does anyone know? It would of course be the same size as those black "adaptors" between the tube and the rubber hoses if you know what I mean.

Seems like I asked this a while back, but I couldn't find that post.

Thanks a lot,


Ken
