You problably have a straight pipe with no cat and res. My parking garage in my apartment make their cars CHIRPs but not make it go off when I only have the Brullen exhaust. It would be annoying and pissing other drivers vehicles when you noticed your car doing this. Have you had your car keyed yet???
