Milltek was founded in 1983, and they have grown to become one of the leading manufacturers of performance exhaust systems for a continually growing range of vehicles.
All Milltek performance exhaust systems are manufactured from T304L (Aircraft Grade) stainless-steel; giving you the satisfaction of knowing that their 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.
From 2017, many vehicles have been manufactured with a Particulate Filter to reduce further the emissions from the vehicle. The Milltek Sport Particulate Filter-Back range is designed to compensate for the sound reducing qualities from the particulate filter and significantly improve the sound aesthetic of the exhaust system.
The Milltek Sport range of Cat-Back systems are perfectly suited to cater for anyone looking to improve their sound and aesthetics, designed as a direct replacement for the original system, available in multiple configurations enabling the owner to choose the increase in volume of their exhaust and/or add a more suitably aggressive tone. All products are made from 304L Aircraft Grade stainless steel. This quality material will ensure that your Cat-Back system will last through any harsh conditions.
The Milltek Sport Large-Bore Downpipes are perfect when looking to improve both performance and sound. These downpipes are fabricated with a larger diameter than standard OEM parts, meaning that there is significantly more space for more gas to exit the engine and pass through, increasing efficiency. Used with the Milltek Sport Catalyst Bypass Pipe, you can expect significant power-gain without any restriction on gas-flow made by a catalyst.
