Sounds fine to me but the S1 pipes are noticeably more quiet, especially when you were revving it up in neutral compared to other exhaust. Also more quiet than the WD baffled I put on but you have not popping or cracking which makes sense since you are running a more restrictive straight through baffle. I thought about buying a used set of used S1 pipes but rethinking that now, I think they may be too quiet for me but I would have to hear them in person to really know. I would love to take a quick ride on a X bike with the factory stage 1 pipes because that is the only way to really know if they would be to quiet for my tastes.
