My Corolla started growling badly last year which got me thinking about a large hole and a complete exhaust system replacement. Eh, that could total the car. I crawled underneath and found a loose heat shield up near the front end. It lay on the exhaust pipe and rattled like crazy at low rpm. The proper gap between the two did not look like much and if I could just stabilize the sheet metal it may not be so bad. Being an LBS mechanic, I went to the scrap metal box and pulled a F wheel. Cut the alloy hub out and stripped the guts out. Inserted two spokes. I pushed that hub up between the pipe and the heat shield and twisted the ss spokes around the pipe to tie the hub in place. Acceptable now. Even sort of sounds like a tuner. But it's looks will never fool anyone.
