Default Can anyone identify these mufflers

Can anyone please help, I have no idea what brand mufflers this is on my 06 Road King, my wife and I bought it used with no history but the thing pops alot at idle and going down the road. I am searching for 2 stock mufflers to calm this thing down cause it sounds like crap with the constant poping but runs great, oh and they are ugly too. This is my first Harley and my wife and I absolutely love it. Any help is appreciated. There is absolutely no writing on these things either.

An exhaust leak can cause the popping too.

What tuning do you reccomend, the plugs have been replaced, I have a fuel injector cleaning kit made by OTC that I used to use when I was a technician, I still use it on my cars and friends cars. Any other areas I might need to check or clean?
