Sounds pretty good for an iPhone video. I’ve been looking at the same exhaust for a MY18.5 RS169. Keen as mustard after seeing your fitment. Cheers. 

I have recently had fitted the Scorpion cat back resonated exhaust. I hate any drone, so initially I thought I had made a mistake with this exhaust. It tended to drone quite a lot when accelerating. With steady revs it was okay and it also sounded nice when putting your foot right to the floor when really getting a move on. It was just the drone when accelerating at a reasonable pace that annoyed me. I know exhausts tend to settle down over a few miles, so I kept my patience. Done around 700 miles now since it was fitted and I am very glad to say, the annoying drone that bled my ears has all but gone. I can now enjoy the sound of my motor without ear plugs. Lol.  It's all down to my age, as you youngsters would probably have loved it when it was first fitted!
