Baffles

I have Big Louie Slash-Up slip-ons on my 2011 Limited Ultra. I ended up with a 2.5 baffle because I heard that I couldn't use the 3.0 in the slip-ons, but I've read about guys who have them on their bikes. Why can't I use 3" baffles in my Big Louie slip-ons? If I can, I'm gettin' some. Also have V&H Power Duals.

It sounded amazing but was to loud for my ears. Very difficult to tune and low-end (TQ) power can suffer. It is possible, we just don't recommend it. The 2.00" and 2.25" work best with true duals or power duals. That recommendation is based on performance, tuning, and volume. For most people the 2.50" with duals is to loud for long rides.

Thanks for choosing Rush! Let me know if I can provide any other info.
