You'll notice a big change in the exhaust tone with the 103 vs a 96. The 103 is louder and has a more aggressive sound. The Louies are a bit deeper but you can still expect the classic Rush deep/solid tone. They use a very similar baffle design to our 3.5" slip-ons. I would still recommend the 2.5" baffle. Thanks for choosing Rush!

I also have the 2011 Ultra Ltd. Someone said at the dealer they need no tuning. Is this true that we can just slip them on without hassle? Also, does the prices for the tip models include your choice of 1 tip in the price? Thanks!

 

I put the Big Louie's with 2.00" baffles on my 11 SG with stock header , and the right side muffler turned brown after 200 miles. Guess i should of put 2.25 or 2.50 on...: (

 

With a 2011 and stock headpipes, we recommend the 2.25" or 2.50".
One the 2012 and stock headpipes the 2.50" will work the best.

Did you purchase the pipes from a dealership?

I heard that the 2.5" will pop on decel with stock a/c and no remap. I ordered mine from the dealer and will be receiving them tomorrow. Can't wait to put them on but worry about the poping. Any suggestions if I have this problem?

 

Which baffle would be louder? 2.25 or 2.50?

 

The 2.50" is louder. We now offer an even louder 3.00" baffle that is only for cat back use. No tuning required. It's the loudest slip on we offer for new stock touring bikes!

I've had Big Louies with a 2.5, and really liked them. Last year, I switched to V&H High Outputs because I thought they were a deeper tone. They're not bad, but I could stand more loud. Think I'm going back to Big Louie Slash-Up to match the contour of the bags & fender that I did in March of this year. My question, can I get a 3" baffle for the chrome Big Louie Slash-Ups, for my 2011 103 Limited Ultra? Have V&H Power Duals also, and would like to keep them. If no 3" baffle, I'll go with 2.5. Thanks.

 

I gotta say after having V&H true duals with oval slip ons on my last bike it was definately a different sound to get used too with a Fuel Moto 2/1/2 head pipe and Rush Big Louies with 2.5 baffle. The bike runs absolutely incredible with this combo! What I have learned is that when you are used to hearing the same exhaust note for years and then do something totally different it takes some time to get used too! I am really starting to love my Big Louies! Nice and deep but not obnoxious. When you roll into to the throttle they let you know they are awake! You simply cannot go wrong with these slip ons! I also have Rush pipes on my 2012 Fat Bob.

 

I've had 3.5" Rush slip on my 80" Road King for years. They have 2.5" baffles. These were very loud on my RK. I just got a '12 SG and put these on it. Very nice sound, just not loud with the stock head pipes. Hopefully have new head pipes on before Biketoberfest.
