Quiet exhaust that performs well

[GW's Motorized]

I'm looking into doing some exhaust upgrades that are less restrictive and is quiet. I am usually riding my bike around 7am on weekdays and I want it to be quiet. I have access to welders and can combine parts if needed. Any suggestions help.

My ebike is so quiet I can't here it over the tire noise. But my gas bike with stock muffler is pretty quiet to. I think it may be hard to find a muffler that does both

GW, performance and quiet is the Holy Grail of mufflers, good luck Bubba.
