Default Anti Reversion Cones?

I have 07 Heritage and I'm running the vance & hines big shot longs and thinking about using the anti reversion cones in my exhaust head. The problem I'm trying to clear up by using them is my pipes are poping real bad on deceleration and the vance & hines really have no good tone to them they just make a deep roar sound. I might even try removing my baffles with the anti reversion cone trying to find a tone not just a roar. Any one using a similar set up

Try quiet baffles... but popping is going to be there unless you tune it out using some tuning device (download, pcii, sert, dfo, fuelpak, etc...)

Make sure your headpipes are secure to your motor. They tend to loosen up at the heads.

anti-reversion aka power cones, break up sound waves that travel inside the pipe. think of these waves as a slinky. the slinky stretces out and then rebounds. the waves move back and forth in the pipe. now think about putting a bolt into the middle of the stretched slinky. the rebound stops. Power cones help deliver more power in straight pipes. They do nothing on pop or sound issues.

I think instead of the ar cones, you can put a thumb screw in the muffler. Same effect as ar cones, but one tenth the dinero.
