It's a different muffler altogether.
One of the things that brought Alpha down was the muffler supplier they where using for their custom setups (not the variable) would not stand behind their product when a large number started to fail as shown above, compounded by Henry farming out production work to keep up with demand rather than maintaining in house quality control.
Alpha was one of the originators when the Slingshot was introduced. Henry jumped in with both feet and everyone else followed. A business can do a 100 things right and help 100 people but when it goes South that is all most remember. Unfortunately some bad decisions made what was a stellar reputation and pillar of the community sour really fast and he could have handled the end result better.
So that is where some of the comments are coming from. Not defending the way it went down, just prefer to remember the early work he did and willingness to help.
