I want to add Rinehart 4 inch slip ons to my otherwise stock 13 Ultra Limited. I'm looking for a deeper exhaust tone. My question is by adding the slip ons do I need to make any tuning adjustments or will the bike still run OK.

Should be fine.

 

Slip them on and take off.

 

really depends where your at now.most bikes come off the line very lean to pass EPA standards.if the bike spits when cool or when trying to accelorate,it`ll need to be tuned (even though giving it a good tune will only make it run alot better even if not totally necassary)
