Catalytic Convertor Question

[Jamie_DTR]

Ok, I was under my car over the weekend looking, and it looks as if there are sensors plumbed directly to the cats. Is this right or are the lines for something different? If they are sensors, and I remove the cats, what happens to the sensors? Do you mount them somewhere else or eliminate them altogether?

V8Mustang, can you REALLY experience 10-20 hp increase by adding a high-flow exhaust? Seems high, but I'm not that familiar with how cars are. I know snowmoiles extremely well, but cars are a little different. When you refer to a "high flow x or h cat pipe" is that just a configuration of how the exhaust is layed out or is that a model name from a company?

Thanks for all the help, guys.
