To be fair I wasn’t cruising, I was flooring it on a dual carriageway near me to try it out accelerating up to 70-80mph and it was pretty damned loud. I’m sure cruising along at 70 it would probably have been fine. Not tried it with just then smaller part out yet as I’ve messing about trying to bleed the coolant to get the heater to work properly on the passenger side.

Have now settled for both bungs in, but the big one has been cut down to about the same size as the small one. Makes it louder but doesn’t hurt my ears at 5k revs any more. Everyone that has been in it says it sounds amazing.
