Noise wise it's nice. I'm only running it with the baffle in. I think it would be too loud without it. Lots of nice pops on the overrun too. But it's not so loud that I feel embarrassed by it in towns, villages or out on the trail, and I am a bit sensitive to that sort go thing. I rode one with a leo Vince 2 into 1 with no baffle and that was too loud for me.

I installed all the mods and rode the bike a few times before I fitted the can. The mods made a difference, but for me the magic only really happened when the can went on. Then it all came together. I rode mine and a standard bike back to back this week, and on mine, we both agreed the power came in earlier on mine, lasted longer (Effectively a wider power band), was smoother all over and especially on a constant throttle at say 50kph, and mine makes a very nice noise!

The Exan is nicely made and very light, makes a nice noise but is not too noisy.
