Hi - I bought an '09 200 full fat a few months ago from a Renault dealer and have a question. Cracking car by the way. Anyway how do I tell whether it has the OEM exhaust or not? The current one is a) loud but not in a good way and b) ends in a narrow diameter exhaust inside the large OEM end pipes in the rear bumper but is not connected to them. Obviously if it's not an OEM exhaust that probably invalidates my insurance! Thanks in advance for any help.
