Also I'd like to add, I've been doing tons of reading on these types of electric pumps. I was hoping to find someone that's tried this or heard of someone that did. The only real things I can find are like the pump I originally posted in the OP.
I've not heard of the exhaust evacuation before though. I assume it just feeds of the scavenging effects? I've got electric cutouts ahead of my mufflers, but I'd still have the mufflers in place though. I will read more up on the idea though. I appreciate the idea.
