Ceramic monolith catalytic converter

Fitting Kits - PLEASE NOTE
Fitting kits are only available with a front pipe or catalytic converter purchase - we supply them at cost for the convenience of our customers.

Not all kits contain gaskets as some are main dealer supply only. Where we supply a kit without a gasket the original can be reused with care and a little silicone sealant.

A basic kit comprises those parts that will certainly need replacing. You will need to reuse some parts (e.g. nuts and bolts).
A basic plus kit also contains replacement nuts and bolts - in our opinion the small extra cost is worth paying.
A full kit in addition to the parts in a basic plus kit contains replacements for all the mounting hardware (e.g. hangers).

Available fitting kit options on this part: Kit 1: Basic Kit 2: Basic Plus
