heh my car has started running rough at idle. My car is really low and i think i have being hitting the exhaust before the cat. There is now a poping noise (air escaping) from the exhaust manifold. If i get extractors do you think this noise will disappear? Or could it just be the flange gasket? :?: please help thankyou

Could be just Flange Gasket I had a small leak in mine and it was a crack in flange got it welded up now no more popping noise on idle when idling rev it a bit and listen you will hear the leask for sure when u up the revs a bit to see if it is flange leak Some original photos have not been recovered yet.
