I've got a piper downpipe and sports cat on my vRS. However last year it past its emisions by .1%. im a little bit worried that its going to fail this year and im wondering if the cat is on its way out. I did send off the Warranty info but i never got anything back. Should i have? Just wondering if i can replace it under warranty instead of paying another £400

they might argue that a sports cat will have high emissions? I'd drop them a polite email and see what you get in reply. If you have a receipt you should be covered for warranty.

Do they classify the sports cat as a performance one? If so, it looks like it has a 6 month limited warranty.
