> IMHO, an exhaust modification that adds more than 10db to the factory provided one should be illegal. It's easy to think of next steps for cars that are made noisy in the factory, but it's incredible that nothing is being done about this. In Europe cars have to pass an annual technical inspection to renew their license. Every part on the car has to be homologated and they'll only homologate things that are within all safety/noise/etc regulation. My sister's ex boyfriend had to remove his modded exhaust and reinstall the stock version every year before inspection. This is clearly annoying so most people wouldn't bother. It also comes with heavy fines should he ever get pulled over for speeding or street racing. Cops love to hand out additional "illegal car mods" tickets when they're annoyed. Added bonus: This would also solve the American problem with lifted trucks and LED headlights. Unfortunately it would also make my motorcycle unregisterable (not the exhaust, other stuff like distance between indicators).
