Hey,
Is it legal to apply one's own unorthodox methods in order to repair a car's exhaust system? This guy I know has a problem wth his exhaust, but he just wants to use his own clamps/wires to fix it. If he then takes the car in to get his brakes fixed, are the repair people obligated by law to file a report about the owner's own jerry-rigged exhaust? This is in Illinois.
Thanks!
