It sounds delicious! A nice burble at tickover and, so far, it sounds great under light acceleration too. That's with the baffle fitted, I must try the alternative when I'm finally legal.I'm very tempted to get the same one as it looks and sounds awesome (at least accd. to the one video I found with a 2016 SV650 which the company posted) and is not too expensive. How do you like the sound? Do you get some nice deceleration popping as well?
Does the black stainless scratch easily?
Which brings me to your second question. I haven't started, nevermind completed, my basic training course yet, so I can't tell you what the overrun is like and whether it pops and bangs in either guise, but I hope to Christ that it does! All will be revealed when I finally have the necessary qualification to venture out onto the local roads. Until then I'm just getting used to low speed manoeuvring and general smoothness.
But the finish of the pipe seems to be pretty decent, I certainly didn't mark it during fitment and the end result is very satisfying to behold.
