Hack Engineering Catless Downpipes (F8X M2C/M3/M4)

£329.00 £299.00

Hack Engineering Catless Downpipes for the S55 engine as found in the F87 M2 Competition, F80 M3 and F82/F83 M4.

The secret to unlocking big power on the S55 engine (and many other modern BMW engines) is to remove the restrictive catalytic converters, which also allows faster turbo spool and reduced engine bay temperatures, as well as a deeper exhaust note. These downpipes fit directly in place of the originals, allowing greater flow for those all-important benefits. Remap required after fitting – with tuning, benefits of 60+bhp and 70+lb ft can be expected.

Constructed from 3″ T304 stainless steel, fully TIG-welded and laser-etched with the Hack Engineering logo. Priced per car set.
