Are they louder than the Conquest Customs Octanes?
my buddy with a street bob (103in, I believe) has the bassani equivalent of the octanes...they are louder than my freedom performance curved radius for sure...honestly, they are super fucking loud and they backfire like hell...he's had his bike on the dyno twice, they cannot tune it out...the blue flames that shoot out of them at night are badass though...I wanted them, still do, love the way his bike sounds, especially at start up, but I wasn't waiting 2-3+ months for them to ship to me.
The fp curved radius are loud, but not obnoxious, my other harley friend took mine out for a spin and I loved the way they sounded as he hammered it through the neighborhood. If you're not on the throttle all the time (like I am) they sound great without being overly loud, but you can definitely tell I am coming. I've heard no complaints about them, everyone says my bike sounds perfect.
I am very happy with my purchase of the pipes and I got them for dirt cheap ($544!!) from BTO Sports with free shipping.
