Description

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. Requires a Stage 2 ECU remap and must be fitted with a Milltek Sport cat-back system.
