BMW Z4 sDrive35i: Development Completed

Milltek have just completed development of a stainless steel performance cat-back exhaust system for the new BMW Z4 sDrive35i.

The Milltek system uses larger, full bore twin 63.5mm (2.5-inch) pipework and acoustically efficient silencers for better gas flow. The system is finished off with dual GT100 (4-inch) tailpipes that were selected specifically to look like they are part of the original design of the car and not to look like an aftermarket add-on. While subtle, they do still hint at the extra performance on offer.

Additional power and a razor-sharp throttle response is, in part, due to the Milltek system replacing the restrictive secondary catalysts. There are four cats on the standard exhaust system, two primary and two secondary. The two primary cats are regulated by the engine's ECU control unit but the secondary cats are not so can be removed without requiring an ECU remap.

More information, photos and videos will be available here very shortly...
