Akrapovic Slip-On Line (Titanium) - G20 M340i

Akrapovic's Slip-On Line replaces the rear of the M340i's exhaust with a titanium system and carbon fiber tailpipes. It adds a second exhaust valve to the factory one and comes with the controller to run it, so the car has a wider range between quiet and loud.

What you get

• Titanium construction that is lighter than the factory rear section.
• Hand-made carbon fiber tailpipes with two acoustic reflectors that send more sound into the cabin.
• Two valves instead of one, with a TNG controller included to operate the extra valve.
• Two resonators, one on each side of the central muffler.
• Measured gains of 4.6 hp and 9.1 lb-ft at 2,650 rpm on Akrapovic's dyno, tested on an M440i.
• ECE type approval, with no remap needed.

Good to know

• An extra BMW valve actuator (18 30 8 686 640) is required to install it and is not included.
• Akrapovic lists this version for OPF-equipped cars; non-OPF cars use its Evolution Line instead.
• In-cabin sound control needs the optional Akrapovic Sound Kit.
