What do you think of my new exhaust?

Velocity stacks have thier familiar bell mouth shape, (actually a hyperbolic curve), for a very specific reason. It increases air flow. The socks interfer with the shape and flow. However, having both velocity stacks surrounded by a filter box leaves the openings open, allowing them to suck air better. The filter box also allows the stacks to feed each other through the overlap inherent in a rotary engine. If you look closely at the bottom inner llip of the stacks at idle, you may notice tiny drops of fuel that have collected. That's because the overlap can spit the fuel mixture out of the carb.
