My best bud has a '09 Ultra, and I usually follow him when riding. I have to say the stock exhaust from my spot behind him, stinks. Might as well be a GoldWing.

He and I are much happier with his new set up. Modified CVO 4" Ultra mufflers with Fullsac's new CVO baffles.

Now it sounds like a Harley, but not too loud or obnoxious. And they are radio friendly.

 

I found them to be too quiet for my liking. I put V&H Basic slip ons with the stage one AC on mine. It sounds so nice now I could never change it back. Just had the front and back lowered as well seeing that I'm only 5' 7". Now I have a lower center of gravity.

 

Just picked up the 09 RKC the pipes sound ok but will be adding new pipes by spring, bolder is better

 

IMO the stock 09 mufflers sound OK, maybe just a "little" thin though. Recalling a WW1Flyingace thread, he rated the sound of some mufflers in increasing throatiness as ; stock 09's, SE 4" slip-ons, Monster Ovals, then V&H Ovals. Wanting just a slight increase I was debating between the SE's and MO's when I read Saturday Night's review of the MO's being just a little too loud for him. That swayed me toward the SE's, which I just installed. I haven't heard them yet though.
Before next riding season I will install the K&N stage 1 intake along with *some* fuel mod, leaning toward PC V at the moment but am waiting to hear from some that have lived with it for a while. There's no real hurry for me since there's another four months of depressing weather.

 

I can't even remember how an 09 sounds with stock cans or without.... I can remember that I like the headpipe configuration the most with that system and how pissed I am that it won't fit on my 07, at least that is what I've been told. If it did I would buy one just to reroute the pipes away from my legs......even after i have added the Khrome Works slip ons, big sucker and SERT to alleviate the heat.
