This is a guide I put together for the Yamaha Pro-tec WB1 Pipe ,no longer produced.
I received the above image from Pro-Tec directly.
There were 2 pipes made for the Yamaha Waveblaster 701 image (Above)shows ,the other pipe from the one I own .
Pro-Tec chambers came with 1 or 2 cylinder head mounting holes,(on top).
<My exhaust chamber body was the 1 hole, cylinder head mount, 2 arm .
Someone added the other 2, cylinder mounting brackets,to top of pipe>
The exhaust chamber body came with 1 or 2 mounting arms (image Above,shows 1 mounting arm hanging down from exhaust chamber).
I 'll post a picture (below)of mine with the two arms.
The 2 arm chamber below uses a triangle bracket,as the chamber body mounting bracket,not shown above, will post a pic when I receive.
