Hello, since I may have had to give you a good answer to the question of whether it’s good or bad, I’ve had to give you a good answer to the question of whether it’s good or bad. I’ve bought a Ford Mustang GT from the 2013 series. In the vehicle license it’s marked as an imported vehicle and I’ve also got a TÜV certificate and an exemption pursuant to § 70 StVZO and § 47 FZV that’s the exceptions for the light (red side markers) and the immobilizer. Of course there’s also an opinion according to § 21 StVZO as it’s an imported vehicle. So, now on the problem: I have a JLT air filter in it and from Rush tailpipes (possibly also more). Neither the exhaust nor the air filter is included in the report? And the report says: 47, 47c, 47d, 48 – exhaust gases, discharge of exhaust gases, carbon dioxide emissions and fuel consumption, emission classes for motor vehicles have to give you the order 49 – the noise and sound system should be prepared for me.
