It's common for the merged outlet not to be exactly in the middle of the valance. You see it more with twin mufflers. With a single muffler your eye doesn't see it
Thanks, i have managed to align it a bit closer to the middle. But yeah i think it will always be like that. I do have a Turbo/phatboy style muffler also so can always swap. But going to try run this duel setup see what the noise levels are like
