Well, I just did the final stage and removed the baffles from my Custom. I wish that I would have done this long ago. It took less than an hour. I thought it was going to take quite a bit longer. Only two Bells Pale Ale's and I was finished. I really like the deep sound. Louder, yes.....too loud, no. I went in stages, started last month with stage one. Turned out great and was quite easy.
