Install slip on's with high flow or standard baffles?

[azbob09]

I have a set of 4" Rinehart mufflers that currently have the 2.5" high flow baffles in them that I had on my old 2014 TG, but it had more performance up grades than the 2017 TG I have now which is stock.
I think I should change back to the standard (2" or 2.25") baffles that they originally came with before I install them on the 2017 TG.
This way being that these slip on's are the only change I've done over stock, the ECM should be able to compensate for that only change. Or should I just leave the high flow baffles in & put the mufflers on the bike as they are now?
Whats your opinions on thoughts on that???

For a stock motor I think I would go with smaller baffles to help retain the low end torque.

You have to be careful with slip-ons.., You need a certain amount of back pressure [Baffling]...Or all you'll gain is noise and lose bottom end torque.. Noise doesn't equal power.
