Hi people, I have a hole in my flexi pipe causing my x reg 1.0l corsa to drive like a horse pumped with crack cocaine... The local garage have told me that as it is connected directly to the cat, I have to buy a new cat... Unfortunately my 12 month warranty on the cat has ran out a few months...

quick query will a 1.2 flexi pipe fit to my 1.0 cat? rather than get a step up pipe to fit a center section?
