When you pull the pipe running to the exhaust when u remove the smog equipment, what did u use to plug it? I thought i seen somewhere that someone used hose and a bolt on the other end of the hose, but wouldnt that melt? thanks
the one on the back of the heads takes a 9/16 unc bolt I cant remember how long. i put some washers on mine. i google smog removal and found all the info on it
