just installed twin slash ovals on my 06 electra glide. they sound amazing, louder than rounds and monster ovals.just to clarify the rounds are slightly louder than stock,my buddy has them and he's replacing them with ovals after hearing mine. monsters are a lower rumble and sound nice. the twin slash ovals are 20 decibals louder( at 101 dec.) and are they give a great tone. no problem listening to stereo or passenger. youtube has lots of demo videos but, not all bikes are harleys so its hard to get a true listen. in my opinion the ovals sound the best

 

Just wondering what I have... I bought a set off a forum member bought haven't installed yet. They are oval but not the monster ovals, are these what you have?? Do you have any pics and or a sound clip?

 

My review I did not too long ago

i have the ovals and they sound awesome. i'll be posting a clip on youtube in the next day or two

 

I had Ovals on my '08 and loved them. Not sure how they will sound on my 2012 with stock head pipes, but I'm sure it will blow away stock mufflers. They are fairly agressive, but nice.
