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.

 

They look like Thunderheaders

+1 thunderheaders slip-ons

 

+1, from the pics they are Thunderheaders or someone has copied that style.. How do they sound?

 

They actually dont sound bad at first but after the bike warms up it starts to pop alot at idle and highway speeds.

 

Thunderheaders, Love them but your bike needs to be tunes good.

 

An exhaust leak can cause the popping too.

 

good call Apex...also a intake leak could do the same thing.

 

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?
