Milltek exhaust parts for the BMW i8
The i8 cat-back replaces the factory system from the catalyst back. For a bigger change, the sports cat downpipe keeps a catalyst in the system; like most downpipe upgrades, it will usually need an ECU remap.
Active Sound Control for the i8
The Active Sound Control unit is an electronic accessory, not an exhaust part, so it suits owners who want to change the i8's sound without touching the pipework. Other Milltek electronics are in the electronics collection.
