Ok, . All I can say is , "What goes on in Port Huron stays in Port Huron". 
As far as the Vintage at the WS its no open stingers... .We have probably 60 + Vintage entries coming from our circuit all mufflerized. So I have to ask myself, do I want one racer mad at me or 60. Most people will tell you there is no loss in performance adding a (muffler) .. If that is what you call it to get past tech. All you really need to do is just extend a 2 1/2' tube over your existing stinger & about 1 1/2 inch past it That takes the crack sound out of it . ( a dirty little secret you just got me to put in print) Now I'm probably in trouble !! MMR
