I fabricated this straight pipe. Do I need some sort of baffle?

Harley shop sells from drag specialities, insertable baffles...you’ll have to drill a small hole....they’re about 10$ each...different sizes too....

I make pipes all the time. to be honest, i don't really find them loud. now if you go bigger than 5hp, volume really changes. but 4 and 5hp motors aren't that loud with straight pipes, in my opinion. But that said, the end of the pipe does make a difference. If it bents a bit, as seen in the picture below, the volume is lower.

I'll ride it as is for awhile and get used to it... nice bike, what are you using for a carb there?

i make intake manifolds and use a PZ style slide carb on all my bikes. it's free performance and the throttle is nice, not so on/off ish, if that makes sense.
