Question: Flex vs. Solid Uppipe

What is the difference between the flex and soild uppipes?

Flex uppipe-> flexes
solid uppipe-> doesn't flex

:)

Well...kidding aside, that is the only difference. If you buy a solid uppipe from a reputable manufacturer, you shouldn't have a significant exhaust leak problem. With a flex uppipe, even if the manufacturing tolerance is not so high, it should be forgiving enough that exhaust leak is minimized/eliminated.
