Ok so the latest in my mustang problems is a pretty bad exhaust leak. It almost sounds like its either the passanger side header or h pipe.The only part of the whole system that is fsctory are the headers. Are they prone to failure after awhile? Is there a certain spot I should look? I poped the hood and it ddoesn't sound like it could be a gasket and ir sounds like its more under the car. The h pipe and cat back is aftermarket no cats. Its not welded up there either. Could it be where the header connects to the h pipe? My cars also lowered and therws a few dings and dents throuout the system. It sounds like a pretty big leak completly changed the tone of the exhaust and it sound like ass. Almsot embarassing lol
