All Milltek performance exhaust systems are manufactured from T304L stainless-steel; giving you the satisfaction of knowing that our products are meant to last within some of the toughest environments. T304L is a highly durable form of stainless-steel that is far less susceptible to degradation and discolouration than many others of its kind, while it will last almost indefinitely.

Additional Info: Fits both OE and Milltek Sport Cat Back Systems - Requires Stage 2 ECU Software - NOTE to Customers - Due to Design of Turbo Waste Gate fitting a decat can cause metallic rattle to be heard more than the OE Cat Downpipe
