Milltek has been developing exhausts for BMW since the early E-chassis era, and the current catalog covers most of the tuner-relevant platforms from the E46 M3 through the G87 M2. Cat-back systems, downpipes with Hi-Flow Sports Cat, secondary cat deletes, and ValveSonic active-valve systems are all available across the lineup, with the deepest coverage on the M240i (F22 and G42), M3 and M4 (F80 / F82 and select earlier chassis), M135i (F20 / F21), and M2 (G87).

BMW fitments split along a few lines worth knowing before you order. Pre-OPF/GPF cars — most US-market N55 and early S55 M3/M4 — can run the full Milltek range including decat downpipes and non-resonated cat-backs. Newer S58 and B58 platforms sometimes require OPF-back or OPF-bypass configurations instead of traditional cat-back + downpipe; the product pages call this out. On valved chassis like the G42 M240i and G87 M2, Milltek's ValveSonic systems preserve the factory valve motors and drive-mode behavior, so the car still quiets down in Comfort and opens up in Sport.

For the full brand catalog across every Milltek product family, see the main Milltek Sport page. To shop by product type instead of chassis, the Milltek cat-back and Milltek downpipe pages are the fastest filter.
