You can remove the baffel, that little holey pipe. Most

of us took a hole saw fitted with some sort of extension and drilled out the baffel, plate, etc. Some have welded an extension to the hole saw. One was sent from one menber to the other for months. I just welded a pipe on a hole saw and it worked well. It's pretty loud with all the baffels removed. Mine had three baffels.
