Is the Supersprint Complete Left Downpipe one side or a pair?

It is one side. The Complete Left Downpipe with Sport Cats fits the left turbo only, and Supersprint sells the right side under its own part number, 529221. A full set for the S68 V8 is one of each side, so order both part numbers if you are replacing the downpipes on both turbos at once.

What is the difference between the complete downpipe and the upper and lower sections?

Supersprint lists two downpipe routes for the G90 and G99. The complete downpipe is one piece per side from the turbo to the front section. The alternative is an upper section with Sport Cats for each side plus a separate lower pair. The complete piece means fewer joints and fewer parts to order.

Does it fit the USA M5 and the M5 Touring?

Yes. Supersprint registers this part for the USA-model G90 M5 sedan and G99 M5 Touring, and for the versions of both cars with the particulate filter. One part number covers all four registrations, so no different code is needed for the Touring or for a car with the filter.

Are the oxygen sensor bungs included?

Yes. Supersprint supplies a threaded bung for the oxygen sensor on this downpipe, so the factory sensor has a place to mount. The sensor itself is not included and is carried over from the car during installation, which is part of a normal downpipe fitting on the S68.

How long is the lead time?

Supersprint lists this part as availability on demand, so it is built to order in Italy and the lead time is confirmed when the order is placed. Bulletproof Automotive lists it on backorder with notification, so you are told as soon as the build is booked.

Description

Supersprint Complete Left Downpipe with Sport Cats for G90 / G99 BMW M5

Supersprint’s Complete Left Downpipe with Sport Cats for G90 / G99 BMW M5 is a one-piece section for the left turbo of the S68 V8, running from the turbo outlet to the start of the front section with Sport Cats on a metallic substrate built in. Supersprint makes each side as its own part number, so a full set is this left side and the matching right side. It is the simpler of the two downpipe routes Supersprint lists for the car: one piece per side and nothing further to order below it, where the alternative splits each side into an upper section with Sport Cats and a separate lower pair. Supersprint designs it to work with the factory front section, which makes it the choice for an owner who wants to start at the turbos and leave the rest of the car standard.

About Supersprint

Supersprint has built exhaust systems in Mantova, Italy since 1955, designing and manufacturing in house rather than assembling bought-in parts. Piping is AISI 304 stainless at a nominal 1.5mm wall, mandrel bent and TIG or MIG welded to CNC machined stainless flanges 7mm to 12mm thick; AISI 310S and Inconel come out where thermal load is highest, and catalyst hardware comes from HJS. Every application is developed against a baseline measured on the AWD MAHA dynamometer in Mantova, which is why the catalogue is model specific rather than universal.

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.
