Love my 4.0 Dyno Tuned, and have heard the 4.5 Pro touring pipes. I do not see a dyno tuned 4.5 on there site. They both have a nice deep tone when you get down on it but no drone at highway speeds, chrome is good, and holding up well after about 7k on them. I am running them with Vance and Hines power duels headers, and powervision tuner.
I have a full setup from fuelmoto. The stage 1 intake, ceramic coated head pipe and 4.5 pro touring slip-ons. I can't say enough good things about this setup. I also purchased the dynojet power vision with maps from Jamie. It all worked seamlessly.

I have the 4" slipons on my RK. Really like the sound and when combined with the hiflow aircleaner and the tuner from Fuelmoto there was a noticible increase in performance and quicker throttle response. The finish is nice but the one thing I dont really like is that the flare out of the muffler doesnt start right at the end of the heatshield on the right side... Its like an inch or so before the muffler body starts and it bugs me.... No big deal but I notice it.

I'm running them on a stock header (see below for bike specs) and I disagree. Too loud and drone like crazy. Mine are for sale (local only.) I will say they are pretty and of excellent quality, just not for me. I will admit I've run true duals since the bike was new and just changed to these. I really do not like all the sound coming from one side......could be why I'm not fond of these mufflers. Will be ordering true duals from MGS in the next few days. (4th exhaust system if you count what it came with! )

Great mufflers, a bit louder than the 4.0's IMO. They also do a Jay brake kind of sound during decelleration. Had mine for over two years and they look and sound great.

The sound coming frome one side has nothing to do with the mufflers. That is due to the design of the 2-1-2 head pipe design. Stock or afyermerket. Only way to cure that is to go true dual head pipes

I have them on my bike now, and I think the sound is just right. The have some bark when you get on it but at highway speeds no drone in my opinion. But each person has their own level of comfort when it come to that.'
BTW...am thinking of selling mine and going to a 2-1 Dragula system to better match the 107 build I just did.
