whats up with the catch cans that have breathers and the ones that dont? i called sts up and they said i didnt need one with a breather...had a friend who blew his dip stick out and he said it was because he didnt have a breather......so do i need one or not?

 

I don't know if they have check valves......

If they don't and you are running with a MAF you do not want one with a breather.

 

alright cool, just figured id check, appreciate it man
