...I just purchased an ST G-90 for my Aeroworks Edge 540T but as the original poster stated, that muffler is so ugly. Also too big. I'd have to cut a lot of the cowling out the bottom just to fit it. So I was instructed by a few fellow RCU members to purchase the MACS bolt through 1 piece muffler. I am waiting for it to arrive from Tower but I am sure it will be a much nicer fit and look. Also the black finish will look awesome against the red and white bottom.
Steven,
This Macs One-Piece is neat and pretty light.
Some people also expect it to add power and even call it 'a one-piece tuned-pipe/silencer'...
It is not!
Compared to the standard, ugly, drop-off ST muffler, which has a huge internal volume for gas expansion, this Macs unit may even make your engine lose a few hundred RPM.
I hope it doesn't.
