Wanted to show off the new exhaust. I also drilled out the cat. The sound of these things are pretty awesome.
Idle, a nice rumble.
Easy acceleration, not to load a little higher pitched, still a nice sound.
Cruising down the road, nice quite low tone. Still hear the radio easily.
WOT, loud as heck in a nice way.
When you release the throttle, the low tone is amazing. Sounds like the bass part of the old THX certified intro on the movies, old age alert.

Disclaimer; this is my opinion.

 

I have the same ones and really like them

 

just wait till you get some miles on them , they really sound gooooood

 

They rock for me too, even more with the installation of the V&H dresser dual headers.

 

Happy with mine, sound even better after decatting, and a Fuel Moto a/c and Power Vision map

 

Monster ovals sound great too. Better with age.

 

I had the Twin Slash Rounds with Dresser Duals on my Street Glide. I thought they sounded good, just a little too loud for me. Now I am running SE Fatshotz with a stock header on my Road King. This set up is definately quieter. I would like to hear some Fatshotz with the Fuel Moto 2:1:2 header.

 

I have the same twin slash ovals on my 2011 Street Glide and have to agree that they get better with age.
when i first put them on i was a little disappointed but after a few thousand miles they sound great.

 

Put them on mine with the V&H Dresser Duals, as the miles went on, the sound got sweeter..................

 

I have the same on my ride and love them.
