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: Larger-bore 76mm Downpipes with cat bypass pipes for highly tuned cars. Downpipes feature ultra-durable semi-gloss black Cerakote coating. Must be fitted with the OE cat-back system and requires a stage 2 ECU remap.
