Default Re: Project Incognito

I haven't been able to observe this yet, but have heard that the convoluted shape of electrical (all metal) conduit or gas stove hook-up pipe is a very good muffler.
I am doing this on my E-bike( with the gas engine and alternator) for both the exhaust(after the muffler) and intake (plastic convoluted split wire loom for the intake - going to an air cleaner canister, in my case)
. Haven't run it yet with this stuff on. But the principle seems to be like the chambered off road pipes on the old Corvette I had a long time ago.
Actually, the two stroke should be able to be made quieter than a 4 stroke because there is no valve train noise.
Paul- I think we are going the same direction- max stealth. Kind of like a challenge to see just how quiet we can get.
I want to be thought of as just another bicyclist.
