What do the Supersprint Sleeve Pipes for G20 connect?

The Sleeve Pipes for G20 join a Supersprint rear to the factory exhaust behind the particulate filter. Supersprint lists them only in that system, so the rest of the car keeps its original front and center sections, and the rear is the only Supersprint section apart from the sleeves.

Do I need them on a USA-model M340i?

No. Supersprint registers the sleeves only for M340i, M440i and ALPINA B3 models with the particulate filter, which are European-specification cars. A USA M340i or M440i uses the Supersprint front section and Center Pipes Kit 527013 ahead of its rear instead.

Do they fit the G26 M440i Gran Coupe?

Supersprint does not register them for the G26 Gran Coupe. Its list is the G20 and G21 M340i, the G22 M440i Coupe and G23 M440i xDrive Convertible with the particulate filter, and the ALPINA B3 sedan and Touring, so G26 owners should contact us first.

Are they sold as a pair?

Yes. Supersprint lists them as right and left sleeve pipes, one for each side of the rear. They are T304 stainless, made in Mantova like the rears they connect, so the joint lasts as long as the rest of the exhaust.

How long is the lead time?

Supersprint lists them as availability on demand, so they are built to order in Mantova. Bulletproof Automotive lists them on backorder with notification, so you are told when they are scheduled in Mantova and again when they ship to you.

Description

Supersprint Sleeve Pipes for G20 / G21 BMW M340i, G22 / G23 M440i, G42 M240i and ALPINA B3 OPF-Equipped [528555]

Supersprint’s Sleeve Pipes for G20 / G21 BMW M340i solve a particular problem elegantly: how to fit a Supersprint rear to a car that keeps its factory particulate filter. Supersprint lists the right and left sleeves only in its system that starts behind the factory filter, registered for the M340i and M440i Coupe and Convertible with the particulate filter and for the ALPINA B3. It is the shortest route to a Supersprint rear on those European cars, with the front of the exhaust left as BMW or ALPINA built it. Owners of USA-model cars, which have no particulate filter, do not need this part.

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.
