Our CAT warranty for the downpipe is two years. Please note that we only approve warranties for CELs thrown because of the catalytic converter.
If a CEL is thrown because of our catalytic converter, we will exchange a new downpipe for the customer free of charge.
But the customer will have to cover the shipping costs themselves.
We will send a new downpipe to the dealer that the customer originally purchased from.
The customer needs to send the old downpipe back to the dealer that they purchased from.
After the dealer confirms that they received the old downpipe, then will they send the new downpipe to the customer.
This means if the issue mentioned above occurs, customers can get a new downpipe for free, but for all domestic shipping costs, the customers must cover themselves.
