Camaro SS 2002

I just had longtubes installed today, I drove about 35 miles back home on the highway. Is it possible that I could have already burned my air check valve/s? No SES lights or anything, im just curious if it's still possible? I have restrictor plates coming in 2 days, should I not drive my car until then.

It's possible... Take them out and check. If you can blow air through them the wrong way then they are bad. You can get a tiny of air through, but not very much at all.
