I have a 2014 Ultra Limited. I want to know if I will gain any thing from removing my cat pipes and installing power duels. I plan on installing Screaming Eagle street cannons

 

Yes, performance will improve. If you have not added the SE air filter or some other freer flowing intake, you should do that as well. V&H Power Dual head pipe is about as good as they come but just say no to the SE mufflers. If going with V&H, go all the way with a set of theif mufflers matched to the head pipe, like the Monster Ovals. I would also suggest that you take a look at the Fuel Moto setup. Their 2:1:2 X-pipe combind with their Jackpot mufflers is a proven performing setup.

A Stage I upgrade greatly benefits from a proper dyno tune; highly recommended and well worth the cost of a tuner and tune. Just say NO to the factory ECM flash; a waste of money.
