About OKTAN

OKTAN Performance builds performance parts for European cars — exhaust downpipes for BMW and MINI turbo engines, plus lighting and interior upgrades for BMW and Mercedes-Benz.

Every downpipe is drawn from the OEM part and rebuilt around flow: mandrel-bent T304 stainless, TIG-welded, with CNC-machined flanges for a factory-fit bolt-on. Parts are made to order, and we confirm fitment for your vehicle before anything ships.
