On some Corsas, the cat section is a part of the front of the exhaust system so can be unbolted from the manifold downpipe and cut off the exhaust.
Then it\'s just a case of fitting in it\'s place a decat pipe - normally a straight through pipe with the correct fitting at the downpipe end and tapered at the other end to either go in or over the standard exhaust system.

Other Corsas may have the cat on the manifold, in which case it really isn\'t worth worrying about and the cat isn\'t going to be a source of some hidden power upgrade.
