Your pipes are unmuffled now. They are free-flowing. You are hearing a mixture of 1) exhaust valve noises, 2) air pressure pulses, 3) air turbulence and 4) exhaust pipe resonance from 1, 2 and 3 combined.

That's why I developed the fibrosleeve. It absorbs the higher frequency noises and significantly reduces the resonance of the exhaust, leaving just the deep, low frequency sounds.

I've disconnected/reconnected the battery after a few mods just in case. Plus, many mods are better and more safely done with the battery disconnected anyways.

The backfire thing you are talking about is related to the PAIR valve. Do a search for PAIR valve or depaired. There are different levels of depairing that range from deactivating the PAIR valve system to removing it altogether.
