See all those twists and turns in the exhaust pipe?
Are they just to look cool?
No. They balance backpressure.
One pipe comes off the front cylinder, the other off the back, right?
Each twist and turn creates resistance to pushing out the hot exhaust.
But the resistance must be identical to both cylinders or one would run freer than the other and set up an off-camber vibration in the muffler.
So the pipes must run near identical lengths and also with similar turns before they merge, to balance back pressure to the cylinders.
The designer adds an extra turn to the shorter exhaust pipe
to achieve that balance.
Now you know.
Happy Monday!
