Regarding the discussion about a tapping noise from the engine area that was brought up yesterday, I wanted to ask a question that may shed some light on why we're experiencing this problem. I tightened my exhaust bolts (particularly on the #1 cylinder) a few months ago, now I've started noticing a slight tap and figure it's time once again. Well, while under a friends M3 a couple of weeks ago I spotted an exhaust "hanger" bracket that my car doesn't have. This bracket is attached to the upper passenger's side of the transmission housing and supports the exhaust where the header meets the center section. It seems logical to think that the absence of this bracket could cause the loosening of exhaust bolts at the head and that is my question. Right now my exhaust is only being supported at the head and tail with no center support. My car is an '88 and I was wondering if others of the same year have this bracket and if you do, do your exhaust nuts loosen up anyway. I'm ordering the bracket either way, but just thought I'd see what you guys thought about this. Strange that someone would remove it and not reinstall - Cat. Convertor,Clutch, Guibo, shifter parts, etc. were all original when I got my car which makes me think that my car never had it at all. Am I the only one without it??
