No, 65MPH was fine in mine but once you hit 70-75MPH then it got loud. It also depends on the exhaust too. I had a screamer on it first and it would do your head in so then I changed it for a quieter one and it made a huge difference. Can't remember the name but a tuckaway should do the job nicely. I can't see Ross driving the shit out of it with the roof down. Mac is going to Cork on Friday so he could bring one down to you. Worth a try eh?
