The 2019 BMW G29 Z4 M40i easily gets to 400+ Hp, with the addition of the Supersprint Performance exhaust, and a ECU tune.

The B58 3.0L 6 cyl. engine is heavily restricted by the stock system, being in need of a massive increase in exhaust flowing, in order to reach its full potential.
The Supersprint full exhaust starts with an oversized Turbo downpipe, with an integrated HJS Motorsport, 130mm high volume catalytic, available in 200 cpsi or 100 cpsi versions.
This is the perfect exhaust setup for more conservative and mid-level tunes, up to 400 hp, and 450 Hp, respectively.
Furthermore, we have developed a cat-less downpipe + dual catalytic system, designed and sized for more radical conversions , up to 500+ hp.
This is the ultimate exhaust for the highest performance gains.
As always, each and every Supersprint exhaust component for the Z4 M40i is hand built at our factory in Italy.
