The RPM jump can be any number of loosely associated things. The slight afterburn is an exhaust leak...you probably need new gaskets.

shhhhhhhhhh ... no cats - no leaks - the stink pipe is a full slip joint with welds and the gas flow in mind.

Is it possible that there's a leak from your exhaust gaskets, going into the manifold? surely you didn't weld the manifold directly to the exhaust.
