Slip-On Line (Titanium)
This high-grade lightweight titanium system, finished with hand-crafted carbon-fibre tailpipes, weighs in at 35% lighter than stock and features a pair of collectors cast in the in-house foundry. The Slip-On Line (Titanium) comes with a specially developed Akrapovič control kit for a complete sound experience. The sound character offers a rich tone at normal cruising, rising to a deep sporty sound when the M3/M4 is driven more dynamically. It serves up a perfect sound at all rpms, delivering comfort and sportiness in one exhaust. A ground-breaking octagonal shape has been fashioned from lightweight titanium with a carbon-fibre outer sleeve for the tailpipes, and for more traditional buyers there is the classic cylindrical design.
The system delivers power increases of 8.0 kW (10.9 hp) at 6,000 rpm and a torque gain of 13.9 Nm at 5,000 rpm when tested on the Akrapovič dyno against a BMW M4 Competition with a standard stock exhaust. Remapping is not needed for this configuration, and it fits all vehicles (OPF and non-OPF), but the ECE certificate is valid only for cars equipped with an OPF filter.
Optional link pipes and downpipes are available for customers looking to change the exhaust for closed circuit usage. An optional Akrapovič Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovič Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid. An optional hand-crafted carbon-fibre rear diffuser is also available to add an extra visual impact to the Akrapovič tailpipes.
The exhaust system also fits xDrive models.
The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.
The Tail Pipe Set (Carbon) has to be ordered separately as a mandatory part. Please choose TP-CT/69 or TP-CT/68.

We work closely with our vendors in order to have the product shipped directly to you from their warehouse if that means you will get the product faster.

The earlier in the day the order is placed, the better the chance it will ship that day.
While we will do our best to ship from the distribution center closest to you, not all items will always be in stock in every location at all times. In some cases we will split the order and ship each package out to you individually and in other cases we may need to consolidate the items in one location to ship out as one package. We utilize our best judgment in an attempt to get the products to you as quickly as possible.
Some items will be marked "Available - expect 3-5 business days lead time prior to shipment". These items cannot ship the same day and require lead time prior to shipment. If you select an expedited shipping method, please note that this will not reduce the lead time before the order is shipped.
