Very low tone, I loved the tone, just wasn’t in love with the aesthetics. I put on a Akropovic which was a lot larger and also has a nice tone. I would say the White Bro’s. Is a tad softer tone but not much. I am old and not into real loud stuff anymore. I sold my Spyder a couple weeks ago just took up too much room.
Since it's for/off a 2013 RS, it should at least fit all the 2013 & on V-twin Spyders, they ALL had that style of connector onto the cat or cat eliminator - but anyone looking at fitting it onto an RT might want to check the muffler body's overall length (to ensure the hot exhaust blowing out won't melt the underside of the pannier) and that the rear hanger spaces the muffler body far enough away from the park brake lever (to ensure that lever doesn't rip the crap outta the inside of the muffler as the suspension articulates up & down!)
