Does anyone have experience with DIY-mufflers? The bike currently has one, made by me. It's a bit over 2 kilos at the moment. It gained some weight when I added some extra baffles and a dB-killer to get to my desired noise level. I'm not 100% sure anymore that it's nonrestrictive enough because of those parts added as an afterthought.
I have a new design in mind that would weigh 1600-1800g by my calculations. It'd have 2x26mm OD outlets. I'd anyway appreciate anyone's experiences with silencers. The noise limit for this bike at the closest big track is <95dB @4500rpm.
