What comes with the Boost Logic Complete Downpipes for G90 M5?

The Complete Downpipes for G90 M5 combine the upper and lower downpipe sections that Boost Logic also sells separately, and the product photo shows four pipes. Boost Logic has not published a parts list for gaskets, clamps or hardware, so confirm those details with Bulletproof Automotive before ordering if you need them in the same shipment.

Is it cheaper to buy the complete set?

Yes. The complete set is 1,899 dollars, while the upper downpipes are 1,199 dollars and the lower downpipes are 799 dollars when bought separately, a total of 1,998 dollars. Buying the complete set saves 99 dollars over the two halves and keeps the whole downpipe section on one order.

Does it fit the M5 Touring?

Boost Logic lists this part for the G90 M5 sedan with the 4.4 liter S68 twin-turbo V8. It does not list the G99 M5 Touring, which shares the engine, so Touring owners should confirm fitment with Bulletproof Automotive before ordering rather than assume the pipes carry over from the sedan.

Does Boost Logic publish power figures for the G90 downpipes?

No. Boost Logic has not published horsepower, torque or weight figures for its G90 M5 downpipes, and no dyno results are listed. No gain is claimed on this listing, so plan any calibration changes with your tuner before installing the pipes on the S68 engine.

Should I buy the complete set or just one half?

Choose the complete set if you plan to change both the upper and lower downpipe sections, since it costs less than the two halves bought separately. The upper and lower pairs are listed on their own for owners who only want one section, or who want to spread the work across two stages.

Description

Boost Logic Complete Downpipes for G90 BMW M5

Boost Logic’s Complete Downpipes for G90 BMW M5 put Boost Logic’s upper and lower downpipe pairs for the new M5 and its 4.4-liter S68 twin-turbo V8 on one order. At $1,899 the set costs $99 less than the upper pipes at $1,199 and the lower pipes at $799 bought separately. Boost Logic has not yet published a written description, material, weight or power figure for its G90 parts, so this listing sticks to fitment, contents and price. It suits an owner who already knows the whole downpipe section is being changed, rather than one half of it.

About Boost Logic

Boost Logic was founded in Austin, Texas in 2003 and made its name with Toyota Supra turbo kits, setting street car records at 6speed record days and the Texas Mile that stood long after the company stopped racing Supras competitively. It designs turbo systems, titanium exhausts, intercoolers and engine components for the Toyota Supra, Porsche 911 Turbo, Nissan GT-R, Ferrari and Lamborghini, and its R35 GT-R builds have trapped over 180 mph in the quarter mile and over 200 mph in the half mile.

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.
