I had this custom made a couple of years ago at great cost. Made by unique exhausts, who if you have a google for you'll see have some of the best reviews of any powerflow franchise.
It's all stainless steel. Sounds great, not loud but gives a good growl when you want it. Nice oval tip which IMO makes a nice change to the usual 3" round you see on Corsas.


I've also got an 18month(ish) old cat that I can throw in for free. Or 10 on its own. Flew through an MOT in November.
