After a month of riding with the eBay baffle I will say volume level is great, tone is deeper with no high pitched loud absurdity. No more ringing ears after commuting with ear plugs as with the factory Delkevic baffle.
Performance is unchanged at lower speed and RPM, though I do notice appreciably less power at 85+ MPH highway. Acceleration is slower, tucking down to the tank makes a more significant change in speed and acceleration at those speeds. This bike is geared at 18/48.
I think a longer straight through baffle with packing would perform better and keep decibels reasonable. I may try that eventually.
