Being the owner of both modified Imports and Domestic vehicles, I have personally been witness to officers targeting Imports for review as opposed to the Domestic owners.

Fact is that I was told the reason is because Import owners are more likely to be weaving in and out of traffic which for the older drivers is very dangerous.

As stated before, My exhaust is definitely not the quietest but I have been fortunate not to fly above the radar of perception/

It may seem unfair but that's how some of them base their stops.
