I'm a 1st time rocco owner

I have a 1.8 8v carb version and am looking at fitting a 4-2-1 manifold and an aftermarket exhaust system. But I seem to be struggling to find any reliable info on either. Does anyone know of someone who manufactures a quality manifold and exhaust system for the rocco, seem some cheap ones on fleabay but don't know if there any good?
Would be grateful of any help or advice that anyone could give me cheers
