Got to thinking about the easiest [cheapest] way to get rid of the fitting on top of the header pipe. I called my dealer near Yakima WA and his advice was to buy a
Gold Star" type pipe. But, as previously said; I'm cheap. I noticed that pipe clamps, for short money, are available but they wouldn't be long enough to cover the spot where the fitting was removed [and the hole welded up]. Decided to make a headed pipe clamp that is considerably longer so that it would cover the sin. Took all day to whittle it out of a block of aluminum but it is done and doesen't look too bad. See pictures. Also found that the discharge end of the header pipe has a baffle in it! As you might guess that piece of junk didn't last long. Heck of a job to grind off the welds. Tomorrow I'll find out if it sounds any louder.
