Love my Thunderheaders too.

 

don't forget that the volume control is in your right hand. my rineharts can howl, but that's only when i'm using the throttle agressively. it'd be tuff to try to keep the thunderheader quiet though, cause they sound so great. my next will probably be a 2 into 1, and am trying to decide between the thunderheader and fatcat. congrats on your new pipes.

 

I love mine too, and get a lot of compliments on their sound.

I love it when they set off car alarms.

 

They are loud but awesome.....I love them.......and yes they are loud on long trips......but i use ear plugs for them....

 

I bought my 09 Ultra, used, with thunderheader slip ons already installed and tuned in. I thought that the first thing I would do is change them out but the performance is very impressive, and they are really not too much louder than my friends Reinhart true duals. I have cruised all day long, 600+ miles in one day and not had issues with the sound. I have put 10K miles on the bike and am going to keep the thunderheaders.
