I have recently installed straight pipes with some tuning done (cams, push rods, heavy breather and a race tuner) on a 2013 breakout.

For many reasons I'm thinking about putting back the original exhaust (V&H slip ons)

I was wondering if i could swap it back without any retuning? Or retuning has to be done?

Your feedback is well appreciated, thanks.

The stock exhaust with the V/H slip-ons will restrict the air flow more, so it will most likely need to be retuned.

Surprised you could get a decent tune with straight pipes. I say put the slip ons back on and it may run better.
