Just wondered if anyone knows if all the Nur spec exhaust bungs are all the same size and if so has anyone got one I could borrow ?
I am hoping to collect my new toy in the next week or two and its loud very loud in fact and I don't fancy a long drive with ear defender's on lol.
Just wondering if anyone has a bung I could
borrow untill I get a quieter exhaust on it.
