I have quiet baffles with vance and hines twin slash 3" slip ons on my 2010 fatboy. The sound is ok but but I want it louder. If I change to standard baffles on this, how much it will be louder--- noticeably a lot? or just a little bit louder? Also, the dealer mentioned that the baffle changes will also require retune or remap, is it true? Or I can simply swap the baffles back and forth any time I want?
Any answers will be highly appreciated.
Thanks

 

It's not that much louder. The biggest difference is when there idle, when on the throttle they are both pretty loud.

You don't need a retune, but it would run better. You'd be better off buying a fuel pak or another tuner and doing it instead of wasting money on HD download

 

If you want it louder, go with V&H competition baffles. They sound good but they are quite a bit louder. You can swap back and forth and I sure didn't have to re-tune.

 

Big City Thunder Baffles! Only way to go!

 

Like Kozy said, louder at idle and cruising around town (where you **** the most people off, haha). Both sound great.

 

give the matting around the baffle time to burn in,the quite baffles then get deeper
