what i would do.

get a receipt for the exhaust you have from scorpion, if youve lost it call them and ask for them to send you one via email, also ask them to put a date to show that youve changed the exhaust for a new one if you get pulled again.

when they see the new receipt they will probably take you off the system, if not then they cant charge you for anything because youve clearly bought and fitted a new one.

if all fails, maybe lower the boost which i would be very pissed off about as i would feel like an inmate in otherwise a free country governed by total nonsense, i wouldnt do it but you may have to, and the other way is to actually buy a new system or mid section to baffle the noise more which personally would piss me off aswell.
