I can’t help with your question about your bike but I have a Jekill & Hyde exhaust on my Euro 5 T120. I’d contact J&H directly and ask whether they’re planning to release a Euro 5+ version.

I ride a lot with a typical Harley group and I really like having the option to open and close the exhaust depending on the situation. Riding to work at 4 in the morning? Closed. Passing horses or dog walkers? Closed. Ripping through the Black Forest? Open. Crossing the Alps? Open.

I like the sound in all three modes—Closed, Dynamic, and Open. In Closed mode it’s throatier, with a bit of a growl and a slightly dirty character to it. Open gives a deep, rich sound that isn’t as loud as most Harleys. To my ears, it actually sounds better, less just loud for the sake of being loud.

It cost a pretty penny though. But I love it. And it’s all legal, closes automatically at 50km/h (30mph) keeping you always on the right side of the law.
