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 Akrapovic 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 Akrapovic 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 Akrapovic Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovic Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid.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 Akrapovic tailpipes.The exhaust system also fits on xDrive, CSL, LCI, M3 Touring (G81), M4 (G83) Competition and Convertible models. The ECE type-approval certificate is not valid for CSL model.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 or TP-CT/73/CF.

Good to know

Questions, answered straight.

If it is not here, call or text the counter. Real people, real answers.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
