Akrapovič BMW Z4 M40i (G29) Slip-On Line Titanium Exhaust System

Manufactured to exacting specifications from high-grade titanium, with components cast in Akrapovič’s in-house foundry, this exhaust system utilises lightweight materials to reduce the vehicle’s overall weight while optimising power and torque across the entire rev range. The system is ECE type-approved and features a design that seamlessly integrates with the car’s lines. The single-muffler layout, paired with four hand-crafted carbon-fibre round tailpipes, gives the rear of the car a distinctive and refined appearance.

The system offers various sound modes to enhance the driving experience. When the revs rise, the six-cylinder engine produces a sporty and animated roar, while in comfort mode, the sound is more subdued, making it ideal for cruising, especially with the roof down.

An optional Akrapovič Sound Kit is available, allowing drivers to control the different sound settings. Additionally, optional tuning opportunities are available through the addition of the stainless-steel Evolution Link Pipe set. However, please note that installing the Link Pipe will invalidate the ECE type approval, as will the use of the Sound Kit.

Fitment and EC type-approval are valid for engine type B58B30C. ECE type approval applies only to cars equipped with an Otto/gasoline particulate filter.

For the installation of the Slip-On system, the stock exhaust system must be cut. Please carefully read the instructions before beginning the installation.

Delivery timescales are given as estimates in good faith, but cannot be taken as precise or exact information. We highly advise against booking installation/workshop time or engaging in preparatory work until you've received and inspected the goods.

What do our stock statuses mean?

1+ IN STOCK in green stock is readily available in one of our warehouses for express delivery (at the time of viewing).

LOW STOCK in green means we're running low! 1 or 2 left on the shelf so act fast. Over evenings, weekends and bank holidays this stock can move quickly so please bear this in mind.

0 IN STOCK in blue means our primary warehouse does not have unallocated stock, but our UK partners do. Often these can be shipped quickly and efficiently. You'll be notified via the Track My Order page if further delays are unavoidable.

MADE TO ORDER in blue means we've partnered with a supplier which primarily makes their products to order. It's not on our shelf, but your order goes into production immediately.

0 IN STOCK in orange means everybody we work with is unfortunately out of stock. Stock is not available in the UK. The best course of action is to place an order to create an allocation from the next batch arriving.

OUT OF STOCK in red. This product is unavailable to order, for whatever reason we're unable to obtain stock or there is an issue with supply/lead times.

We're tuners too!

Our staff are car enthusiasts, we understand the need for speed... This includes getting your orders out the door as quickly and securely as possible!

In some instances, extended lead times are unavoidable. This is as labour-intensive and frustrating for us as it is for you, please know we are doing our best to facilitate your modification goals. Abuse of our staff or systems will not be tolerated.

Thank you, Team PP

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.

Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.

Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
