I have the 2.25" and love them, but I also have a Big Sucker and Fuel Pak.&nbsp\\; They are pretty loud, but I don't notice.&nbsp\\; I also have a shovel with 2" drags, so this bike is quiet to me.&nbsp\\; 2" will work and sound REAL good, you don't want to go any bigger without more air.&nbsp\\; They sell a 2.5" but not good on a stock motor.

 

When I was running Rush mufflers I found that the 1.75's had a kind of throbbing sound that became very tiring on longer rides. The folks at Rush recommended I switch to 2.0's, making the point that while the volume was just a little higher the frequency was very different, giving a much deeper and (to most people's ears) more pleasant sound. I switched, and they were right. Best sound I've ever had on my bike.

Currently running D&D Fatcat with quiet baffle, which sounds nearly as good as the Rush did but give about 8% better performance, according to the dyno.

 

I guess I am getting old, but I have the 2" Rush baffles and they seem way too loud for me.&nbsp\\; I ride with ear plugs but they still seem loud.&nbsp\\; I don't want to be obnoxious to my neighbors or cars that I pass and I feel that my pipes are too loud.&nbsp\\; Of course I have not heard what they sound like to other people.&nbsp\\; I was going to go down to the 1.5" baffle for $70.00 + outrageous TN Sales Tax, but I have decided to go back to my stock mufflers.&nbsp\\; I like the sound but I want to be considerate at the same time.&nbsp\\; 2008 Sportster XL 883L
