A stainless steel turbo downpipe with an integrated 300 cpsi sports catalytic converter, developed and tested alongside the Akrapovic Evolution Line (Titanium) for non-OPF BMW B58-powered models.

It delivers a pure racing sound with great feedback at high revs, without unwanted drone.

• Torque: +34.7 Nm at 2,400 rpm (with Evolution Line)
• Figures measured on the Akrapovic dyno against an M440i with the standard exhaust

Please note: This is an optional addition to the Akrapovic Evolution Line (Titanium) - Slip On Line (Titanium) plus Evolution Link Pipe Set (SS) - for non-OPF/GPF vehicles, sold separately.

Please note: Intended for racetrack use only. It does not meet emissions requirements for road use. An ECU remap is mandatory to prevent engine warning lights.
