Scott Dinger and Randy Smith were the only two after market tube mufflers that I know of.  They both can be spotty on availability and sell out fast when they are. Scotty has a busy weld shop but ping him regularly and he will get back to you. Like the Pickers say, the time to buy 'em is when you see 'em!!

    For a stock muffler, the Tower .40 muffler is lighter than the stock OS unit. The E3030, 843, and one other all are the same size but differ in weight.

Thank you gents!

Jim, an alternative might be a side manifold or elbow and attach a four-stroke muffler or simply use a length of silicon pipe.
This gets the weight further aft if this is your goal.

Well I just received my Enya M-251 mufflers. Very nice! weight is 1.5 oz each. I filed and polished one down to 1.4 oz. Any way, I was wondering what to do with the pressure nipple? I usually dont run muffler pressure so leave it? or remove it and plug the hole with whatever thread size screw?

     Just leave it. It won't affect anything, and if you decide to want to use pressure on an engine, it's already there.
