High vs. Low exhaust, pros and cons?

[Chev.]

The three most important cons are, in this order:

1.   Cost.

2.  Increased noise.

3.  Looks (more tiring, due to being more 'aggressive')

The power or torque increase is absolute nonsense. The only thing you get is a difference in weight, looks and noise compared to the original Yam muffler/exhaust.

 

There's a test on YT that shows it drastically. You may not understand the words (german) but the graphics speak for themselves. They did the testing w/o altering the software.

 

I have another question. What are these spark arrestors for? I can only imagine that no wildfire should be initiated by sparks coming from the exhaust. But there's a catalytic converter in the exhaust system. No spark coming from the engine should pass that.
