Just a quick question, I have a 2013 fatboy lo with stock exhaust. I bought a set of Rush slipon mufflers with 2in baffles. Do I have to re-tune when I put these on? Thanks for any help or advise.

Nope, you'll be fine.

 

Thanks for the reply.

 

I have the same set up on a 13 FLSTF and I get some backfiring when decelerating. The mufflers were put on at the time of purchase and the bike was supposed to be re-tuned at that time, or so they say. Dealer did suggest stepping up to a Stage 1.

 

I'm running with 2 1/4" baffles and was able to nearly eliminate all popping by installing Thunder Torque inserts. In case this might help you.

 

NO tune needed. but a stock bike would benefit from a good tuner and a tune.
