Exaust question?

90$ here
That's not a black Friday discount, just plain old regular price.

It's great for our bikes, we can make the header ourselves.

Oh ok always wondered?
If you want the best pipe suited to your Minarelli setup then the Yasuni r is a great pipe it's not restricted for N.A. sales only the U.K and parts of Europe require that homogenized bs even if it did come with the restriction plate it's easily removed and will way out perform the cheap ebay/amazon jog pipes!
This dyno graph maps some of the best pipes being commonly used on a Minarelli engine with a Mallosi sport 70cc a/c fixed gear,so very similar to our setup!

The Yasuni c16 through 30 are for the variated clutch and higher exhaust timing with over bore setups on the Minarelli, the c16 may work but the 20 and 30 are mostly used with 90 or more cc's.Here is what they look like on a similar setup but they had to raise the exhaust timing and then they fall of hard and fast compared to above but peak much higher yielding a very broad range!
