hey all i got new corsa pipes on my 88 Vette. but when i rev it 3000+ the pipes make a weird high pitch ringing or whine has this happened to anyone before? the pipes where put on by a shop and tac welded into place.

Crawl under the car and see if anything is loose. Make sure the exhaust is not touching something metal.

I don't believe the Corsa exhaust is meant to be welded. Don't know if that would cause a ringing though.
