Currently I have stage 1 SE air cleaner/breather and SE Pro II slip-ons and fuel remap

I am thinking about changing to the Screamin Eagle Pro 16 guage double barrel Exhaust system
because I like the look better and my wife can stop melting her shoes on the mufflers :-)

The questions I have are

1. Any performance differences with the full exhaust vs. the SE II slip ons?

2. Differences in sound. Louder? lower?
I love the sound I have now. Is the full SE exhaust similar?

3. Would I need another remap due to the new exhaust?

Thanks!

Chris
