Akrapovic Titanium Slip-On Line for G90/G99 BMW M5 Exhaust
The Akrapovic Titanium Slip-On Line for the G90/G99 BMW M5 Exhaust is a high-grade titanium system engineered for cars equipped with a gasoline particulate filter (GPF), delivering a lighter, more resonant Akrapovic sound without sacrificing EC/ECE compliance. Complex components are cast in-house, and the system is completed with a mandatory choice of hexagonal or round carbon-fibre and titanium tailpipes (sold separately).
Features
- High-grade lightweight titanium construction, cutting 6.1 kg (13.5 lb) from the exhaust system — a 31.8% weight saving over the standard stock exhaust.
- Complex parts, including the exhaust valve housings and specially designed collectors, are cast at Akrapovic’s own titanium foundry.
- Increased-diameter main exhaust tubes paired with a special control kit that uses valves to shape a refined Akrapovic sound in every drive mode — deep and sporty in character.
- Finished with a mandatory set of hexagonal or round carbon-fibre and titanium tailpipes (customer’s choice, ordered separately), each with integrated acoustic reflectors that direct part of the exterior sound back toward the cabin.
- Verified gains of 5.2 kW (7.1 hp) and 24.3 Nm (17.9 lb-ft) of torque, both at 2,050 rpm, measured on the Akrapovic dyno against the stock exhaust.
- No remapping required on installation.
- Developed for BMW M5 (G90/G99) models equipped with a gasoline particulate filter (GPF) and EC/ECE type approved in this configuration.

Notes
- This system requires a mandatory carbon-fibre and titanium Tail Pipe Set, sold separately — choose either TP-CT/79 (hexagonal) or TP-CT/78 (round)
- The stock exhaust must be cut during installation; this is a permanent modification, and professional installation is strongly recommended
- This system is EC/ECE type approved for BMW M5 (G90/G99) models equipped with a gasoline particulate filter (GPF)
- Installing the optional Evolution Link Pipe Set or Akrapovic Sound Kit (both closed-circuit/track use only) voids this system’s ECE type-approval
Frequently Asked Questions
Does this exhaust require any additional parts to complete installation? – Yes. A carbon-fibre and titanium Tail Pipe Set is a mandatory companion part, sold separately — you’ll choose either the hexagonal (TP-CT/79) or round (TP-CT/78) design.
Does installing this exhaust require cutting the stock exhaust? – Yes. Unlike a fully reversible bolt-on, the stock exhaust system must be cut during installation. Professional installation is recommended.
Is the BMW M5 Exhaust street legal? – It is EC/ECE type approved for BMW M5 (G90/G99) models equipped with a factory gasoline particulate filter (GPF). Installing the optional Evolution Link Pipe Set or Sound Kit, both intended for closed-circuit use, voids this approval.
Will I need to remap my ECU after installing this exhaust? – No. No remapping is needed on installation.
What performance gains does this exhaust provide? – On the Akrapovic dyno, it delivered 5.2 kW (7.1 hp) and 24.3 Nm (17.9 lb-ft) of torque, both at 2,050 rpm, along with a 6.1 kg (31.8%) weight reduction versus the stock exhaust.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only.

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well.
For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at
