Mongo - i put Kurakyn crusher slip ons the standard headers. Sounds very nice - not too loud but will bark if spanked.
also got a Le Pera two up seat (Daytona model) - cut very similar to solo seat but with comfort for a pillion.
Just put my crushers on, and very impressed with them, quiet when you want them to be, and loud enough to wake up the cages when the need occurs, just imagine your throttle hand as a volume controller. Nice deep rumble, good looks, great fit and good quality.
Brash - i sold by 103 Street Bob to get the LRS. Out of the box with standard pipes the LRS 110 has much more pull than the 103 (but is quiet). I put a set of Crusher slipons on (without the tuner) - goes real hard and sounds awesome. Added the tuner after i put the pipes on (didnt feel any real difference).
The motor, brakes, shocks, fork, seat set up on the LRS is a BIG advancement over my 2014 Street Bob Special 103.
you wont be dissapointed.
Ever since I bought my LRS, I haven't touched the StreetGlide, or WideGlide. I love the look, the grunt, and the suspension works better than any Harley I have ever owned, and that is saying something.
