Exhaust leak
Some days nothing works ...
for a long time now ,( over a year) I've had exhaust noise from the rear of the car , I knew there was another donut back there like the one I change in the front , yesterday I decided to do it . got the donut , part number : 17451-23042 said no to the 2 bolts ( mistake) when I did the front , I bought the 2 bolts but they where not so bad , so I tought the rear ones would be OK I broke one ,even with liquid wrench on it snap! car well designed slide muffler off the rubber supports and bring to vise to work on broken bolt. redrilled , retaped , 10 X 1.25 thread , got a regular 10X1.25 bolt at auto part ,( 2$ ) reassemble evrything , and the big roar is still there next day drive for an hour , should be enough for new donut to sit properly , but no, still the big roar of the 1500 cc engine. . roll under , put a small mirror in the area of the donut , then the mirror got all foggy when I put it 6 inches away from the donut , hot air from a leak ,under a small plate ,welded to the tail pipe, bring inside to see better ,just under the small welded plate that serves an unknown mysterious purpuse were 2 holes big as the nail on your index finger , remove plate and using and old piece of exhaust pipe that was too big, I made a patch , got 2 U-clamps and I should be OK for 2-3 years . . What is the prupose of the mysterious plate ???? |

Great repair. That plate look like a heat shield for that flex hose (brake?) just on top of the exhaust pipe on your photo. You may have to put some other shielding in place just in case.
