I am thinking about putting some Rush slip ons on my 2006 flstci heritage.
I was wandering if 1.75's or 2" would be best. I am looking for a good low rumble, but not too loud. Also, what is the part number and good place to look for the best price.
Thanks, Silverfox

 

I got mine from Fuelmoto and had 1.75 baffles. Now the Rushs I just ordered for my dads sporty are 2.0. IMO I think the 1.75 are a little louder and the 2.0 are a little deeper in soud.

 

i had 2.25 and swapped to 1.75 as they provide more TQ but if i did it again i would go 2.0. rush suggest 1.75 with no other engine mods. I did get a dyno tune and they got quieter. the same holds true for my hooker pipes after getting thundermax. when it is tuned it is quieter

 

Jamie at Fuelmoto recommended 1.75s, and said "they are louder than you think". He was right. I like to be heard when I want, but when I'm riding through horse country I don't want to mess with the neighbors. They quiet down when you throttle down. These work for me.

 

Hi Guys,
Thanks for the info. I talked to Jamie today, and he said that the 1.75's Rush should work fine on my Heritage without a remap. I am going to try them with my stock air filter and see how they do. My guess, is they should bolt on to my existing exhaust without any other mods. If anyone can give me any feedback particulars for installation, it would be appreciated.

1.75 baffels any thing bigger and you will have to have it dynoed
