So I now have an exhaust leak at the well known, low hanging, middle flange in my Q300. I noticed it sounding a little different yesterday on startup and put my hand next to it only to feel a draft coming from the gasket in between. I'll see if I can get it on a lift at work sometime this week and check out what needs to be done not only to eliminate the leak but also to bring the exhaust up from hanging so low. I'm not sure if its as easy as cutting, rotating, and re-welding the flange connecting to the downpipe or not. I also prefer to get rid of the middle flange all together and get a pipe welded in instead.
Anybody got any shops that are good with exhaust piping? I think Karim got his middle flange replaced with pipe, like I plan on doing, at Garage5.
