make sidepipe quieter ???
I had to pass the yearly tecnical inspection with my 427 Contemporary Cobra featuring sidepipes. Last year I passed the inspection with under 90db noise, but this year after installing a new cam the volume is up to 96db. Flunked the test!!!.
Have to get back in a week with a quiter car.
Can anybody let me know a quick fix to quiten the exhaust temporarily (just to pass the inspection) ?
Maybe putting in a pack of steel wool , but how can I fix it inside the pipe? I do not want to do any welding.
Help!!!
