Milltek Releases BMW M4 Performance Exhaust System

Respected exhaust manufacturer Milltek Sport has released details of its hand-finished stainless steel exhaust system for BMW’s range-topping M4. As the must-have tuner car of the moment, Milltek has taken many weeks and months of focussed R&D time to perfect a system that balances looks, power and a sublime soundtrack in an attractive package.

Having already created several solutions for other recently released M-powered cars, Milltek’s engineers already have enviable experience in getting the best from Munich’s finest power-plants. Therefore, this new system uses the existing and well-proven EC approved cat back technology, but with the added functionality of Milltek’s latest valve technology, utilising OE spec BMW electronic valves in its construction – still controlled via the factory command systems.

In fact, these intelligent new valves have been designed to seamlessly integrate with the car’s central electronics, enabling a more sporty and aggressive tone when either “Sport” or “Sport Plus” modes are selected, but when the vehicle is left in “Comfort” or “Eco Pro” modes, a more subtle and OEM-esque note is produced, making for sophisticated and refined cruising comfort, even at high speed.

The new system has been designed around carefully optimised dual 70mm pipework which features a thoughtfully calculated 1.2mm wall thickness to ensure minimal weight. Each system is hand finished from aerospace grade, non-magnetic stainless-steel pipework, which in testing, offered the best balance between flow and back pressure for maximum throttle response. Tips wise, the tastefully-styled ?? perfectly fill the M4’s rear valance and are available in either polished or Cerakote black finishes.

Sport catalyst and cat-delete downpipe options are planned for release later in 2015.
