My 2015 Ultra Limited has the Screamin Eagle High Flow Exhaust System that is a 2 1/4" headpipe and 4" mufflers with the Cats in the mufflers and the disc style baffles. The system seems very quiet, but it could just be that my previous bike had a Vance and Hines 2 into 1 Pro Pipe. I was told that you cant add disc, and I guess you could always gut the Cat for more sound. Was just wondering if anybody was running this system and what they thought about it.

 

you do not add discs you take them off for more sound/less backpressher

 

No you have that the wrong way around. You DO add more discs for more sound and less back pressure. Taking discs off reduces sound and increases back pressure.

 

It is like the Super Trap system, Screamin Eagle Doesn't sell discs, so it will be search to see if Super Trap discs fit, or gut the mufflers and get Fulsac baffles for them.

 

I had the SE High Flow system with the Nighstick mufflers. I bought additional discs from Super Trapp and they fit. I'm not running that system now, but I think I had 20 discs on each side. I've still got the system stored in the garage. I'll check and see how many discs are still on the mufflers.

I liked the performance of that system, but wanted a little more sound. My bike is also a '15 Ultra Limited, with a Stage IV kit.
