    either is fine, but you will likely have better performance with baffles. Only way to know for sure, is dyno tune it

    I don't think you can get a baffle in there. Maybe front but not rear. Ideally you want a baffle not sticking towards the end.

    Your pipes are gonna backfire with FSD that's the nature of really short pipes

    Awesome exhaust...I have very little to no backfire. No baffles (I don't think any will fit) because I wanted it loud and yes, they are fairly loud. Great customer service from Frankie!

    Nope...just personal preference to run forward...performance plenty for me and I ride the Dog for style and not necessarily speed.

    Definitely 31 it and I do think it's a 78 main.

    Just will probably need to adjust the carb jets should be fine
