Are the Boost Logic Lower Downpipes for G90 M5 a complete downpipe set?

No. The Lower Downpipes for G90 M5 are the lower pair only. Boost Logic sells the upper pair separately for 1,199 dollars, and a complete set with both sections for 1,899 dollars. Buyers changing the whole downpipe section save 99 dollars by ordering the complete set instead of the two halves.

What do the lower downpipes look like?

The Boost Logic photo shows two pipes in a black finish, each with a braided flex section. Boost Logic has not published the material, pipe diameter or weight, so those details are not stated here. Bulletproof Automotive can confirm them with Boost Logic before an order is placed if they matter for your build.

Which M5 models are covered?

Boost Logic lists the lower downpipes for the G90 M5 sedan with the 4.4 liter S68 twin-turbo V8, sold from the 2025 model year. The G99 M5 Touring is not listed even though it shares the engine, so Touring owners should confirm fitment before ordering.

Is there a published power gain?

No. Boost Logic has not published horsepower, torque or weight figures for the G90 lower downpipes. No gain is claimed on this listing, and any calibration changes should be planned with your tuner before the pipes are fitted to the S68 engine in the G90 M5.

Are gaskets and hardware included?

Boost Logic has not published a parts list for the lower downpipes, so gaskets, clamps and fasteners should not be assumed to be included. Confirm the contents with Bulletproof Automotive before ordering, especially if the installation is booked and the parts need to arrive together.

Additional Information

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.

Shipping Policy

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. Please review the full Terms & Conditions here.

BP Pricing Difference

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 sales@bulletproofautomotive.com with any inquiries.
