As above, be unlikely to be having a significant negative effect.
Not worth the cost of replacement anyway.

True, when i replaced my corsa sport standard system with a duplex exhaust it gained in performance slight.
Is it de-catted and straight through etc?

Maybe why then, as far as im aware N/A engine's need slight back pressure so maybe not enough pressure there? Try sticking a sports CAT on instead
