I just put on a new o/r h-pipe with the little smog line on it. I hooked it all up and when , and only when, I accelerate it makes a loud sound which sounds like an exhaust leak. (but there is no leak). From what I hear it is the smog pump pumping air in and making that noise. Now...can I just disconnect it from the h-pipe, plug up the inlet on the h-pipe, and leave the smog line hang there and stil be pumped by the belt. I also heard something about how it is hooked to the headers or something?? Any input is greatly appreciated.
