Just for reference this is a C+P from milltek FAQ's on there website:
Aftersales Care
Q. Is my exhaust system covered by a guarantee or warranty?
A. As long as you are the original purchaser, cat-back exhaust systems are covered by a lifetime anti-corrosion and manufacturing defect warranty and hi-flow sports catalysts and downpipes are covered by a 2 year or 80,000km warranty. We do not cover against any modifications made to our product after it has left our factory and also not for unusual use of the parts - for example, the use of Nitrous Oxide (NOS), damage caused by going over a speed bump too fast etc. Our warranties are offered on the understanding that the cars power maybe increased by up to 33% from it's original specification. Modifications made to increase the power beyond this will render the warranty void.
We pride ourselves on our after-sales support and customer service and will look into each case on an individual basis.
All warranty cases should be dealt with by the Milltek appointed distributor from whom you purchased the system. However, if you are dissatisfied with the service of your distributor in response to your claim, you can contact us directly by emailing us at techsupport@millteksport.com.
Simply because they are a wear and tear part. Can't see anyone offering lifetime warranty on a CAT.
