??? not very clear but this is what i think ur asking a reply to...
usually an exhust system for a corsa is from the cat back which means middle pipe and backbox....
some people remove the cat aswell, if u change the manifold then I suppose thats what a proper full system should be called but its very rare that a company sells a whole exhust system including the manifold.

2-3bhp gain if ur lucky but ya wont notice it...will make it slightly more responsive and back box might be a tad louder
