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: with HJS HQ 200CPSI Cats (No CEL or ECU Software Required) – Fits to OE OPF/GPF & Milltek Sport OPF/GPF Bypass Sections
