i agree. unless you can show me a cop that drives around with a decibal reader, go ahead and put headers and an O/R pipe on. hell most local shops around me don’t even have decibal readers. i was in this same situation. except i got pulled over for having an illegally modified exhaust which was a fart can on an otherwise stock cavalier. i wasn’t up to knowledge on this when i was ticketed. so i fought it and won.
