chirping exhaust
Hi,
Long time since I have been on here. I got back from overseas on leave and wanted to take my 72 out. I cranked it up and it has started chirping out of the exhaust. Weird sound. Only way to describe it is the sound of a belt chirping. It does not get faster or louder when the rpms go up but when I pull it from P to D the chirping gets less. Only comes from the left side. (hooker sidepipes). The engine is running smooth with no missing. I cant hear anything weird coming from under the hood. I put a piece of hose to the left side valve cover and dont hear any chirping. My hope is that the suspension settled or something after being sitting for a year without being driven and that the left side pipe is rubbing against the frame or body somewhere. Does that sound probable or is there some other test I can do to check any engine piece?
Thanks

So annoying, the sound does change when I hold a rag over the pipe. The chirping goes away when the engine is under load or being revved so it has to be a pipe rubbing just ever so slightly.
and to top it off my starter was dead this morning. ugh. I get 2 weeks before I have to fly back to Korea. I wasn't supposed to be spending it screwing with a car.
