Just bought some corsa mufflers only,  what should I do,  thinking about keeping the 3rd cat until I get a tune so I won't have a engine code.   So should I  keep the resonator or remove it? Would appreciate the info

There will be no codes set of you remove the 3rd cat or resonator,personally have the Corsa cat back exhaust,it just gets to be a (trick or treat)when adding Down pipes to the mix,and thats when the codes will be set if a tune is not added,have the PPE DP from www.ecopowerparts for almost two years now,overall great quality Down pipes which set off (zero)codes and welcome aboard.  Z

Z's correct as the O2 sensors are pre and post the primary cats located in the downpipes. There are no exhaust sensors after the 3rd cat.
