Do you know that PI cars DO NOT HAVE TO CONFORM TO ANY ADR RULES.
Do you that that effectively makes you IMMUNE to any sort of defect - doesn't matter if it's noise, emissions whatever.
Sooo...
I'm thinking I import an R34 GT-R V-Spec and make it fullee... I mean top mount super single HKS T51R SPL, no cat, 115dB muffler, 20" rims, carbon panels, neons flashing all the time, no seatbelts, caged, stripped interior, big fark off venting BOV, Omega stickers all over it and you point to the GOLD coloured compliance plate and the cops can't do shit.
And take a slow cruise down da Chapz...
