hi all just to let you all know I was pulled over on stud road last week on the way back from nizpro for no reason at all, I asked why and he said that my car just looked unroadworthy???? the cop took about 5 picks of my engine bay, flash tuner box, and exhaust system... I then got a letter on monday 9th of feb from the EPA telling me I have to get it tested for emmision control systems and noise!! I sh1t myslef for a bit then called nizpro and told Dave, he said dont worry ill fax you a copy of the ADR complient certificate and it should be all good. so I booked it in for yesterday and after showing the tester the form and 30mins of testing I drove out with a certificate of compliance!!!! so my point is that for all the guys out there with a nizpro stage 2+ kits you have nothing to worry about!!! cheers Christian
