The outlet pipes are plumbed to the two outer chambers. Enlarging the holes in the inlet pipes at that point would allow more direct flow from the inlet pipes to the outlet pipes. I believe some people do this without cutting the muffler apart by grinding away with a dremel attachment down the bore of the inlet.
