<< I can vouch for that Dont get me started tho! If it aint the standard exhaust the car was manufactured with - it's illegal in their eyes >>
Well I would take it to court, police trying it on by the sounds of it.
I would want to know how the hell can they think of doing you for the above, the cars exhaust is a consumable item on a car. It will require changing, after that point its not an original manufactured exhaust, also the likes of Subaru contract out parts to other companies to make money from design/patents rather than on the items production.
So that means that any exhaust other than the one provided by Subaru garage is illegal, so that means all the motor garages including the big chains are selling illegal exhausts.
So when are the police going to shut down these suppliers of illegal goods? dont they do this to conterfit stalls in markets and to drug dealers?
Also if the exhaust meets noise level requirements its within the law in that respect.
Sometime the police are so jumped up
