Akrapovic Downpipe w Cat (SS) BMW Z4 M40i (G29) 2019 2026

Crafted from high-quality stainless steel, with the front part of the downpipe cast in the in-house foundry.

• Sporty 300 cpsi catalytic converter integrated into the downpipe, with stainless steel heat insulation and a flexible tube in the middle section
• With an Evolution Line (Titanium) fitted, power gains of 18.7 kW (25.4 hp) at 5,600 rpm and torque increases of 34.7 Nm at 2,400 rpm, tested on the Akrapovič dyno against a BMW M440i with the standard stock exhaust
• Pure racing sound with great high-rev feedback and no drone

Meant for racetrack use only; remapping the ECU is mandatory to prevent potential “check engine light” warnings.
