I got my MAC ceramic coated long tubes in with the prochamber BUT it appears the long tubes have holes in them for emmissions. I eliminated my smog pump and all that can i just plug the holes? When i ordered them the guy told me there were no emmisions components on them but i guess he was wrong.

Your help is appreciated.

Tahnk you

You could plug them since you did away with emissions.

well, you obviously need to put your O2 sensors in.... but other than that... plug em up

Hmmm are they threaded holes in the collector? Stick your o2 sensors in there, see what happens.

thats the holes for the 02 sensors thats how the macs are made i looked for a set for my car and all macs were like that

theres only one "hole" that would need to be plugged and thats the EGR port... which is located on top of the passenger side header. i just hit mine with a welder, but you can get a cap for it too.


The holes by the collectors are for your o2s. i dont think you wanna get rid of those.

Look close at the holes. On some long tubes the o2 bungs are welded on but the center isn't drilled.

are the long tubes worth the money and do they add more than the shorties
