As the M235i uses a later-spec turbo than the earlier M135i, Milltek has also revisited the design of the downpipe, in order to maximise flow and increase performance. The new part as available either with or without the HJS high-flow sports catalyst, depending on the customer’s application. With the cat fitted, full emission legality can be achieved. Speaking of which, Milltek also has a fully EC-approved version of the downpipe/catalyst in development, which will appease even the most ardent of testing bodies.
The new system has been designed around carefully optimised 76mm (3”) non-magnetic stainless-steel pipework which, in testing, offered the best balance between flow and back pressure for the sharpest throttle response. Tips wise, the tastefully-styled GT90s perfectly fill the M235i’s rear valance and are available in either polished or Cerakote black finishes.
Milltek Sport exhausts are made using type aircraft grade stainless steel, known for it’s high quality and for being less likely to discolour (due to being anti-magnetic). All Milltek exhausts are designed and developed in-house in the UK.
