While my engine has been great (259,000) and transmission replaced at 68,000 doing fine, the exhaust system have started to corode. Took it in to a local shop and they did a quick fix attachment,sound as bad as before, but I fear there may be much corosion in various spots along the bottom of the car. Honday says they can replace the system but parts alone may cost $1200. Anyone have any suggestions as to how best tackle the problem. Really trying to get to 300,000!
