I have UFO with 4 megaphones. It seems a bit loud with the 2 1/2" tips. If I switch to the 1 1/2" tips would it make any difference in jetting or performance? I would imagine the four small tips would outflow the engine anyway. I wonder about the 2 1/2 inch core slamming into the 1 1/2" opening on tip for flow?
