Do the Supersprint Valved Rear Mufflers for G20 include tailpipes?

No. Supersprint makes the Valved Rear Mufflers for G20 for the factory tailpipes, which are moved across from the original rear. The car keeps its factory look. For Supersprint tailpipes on the M340i, the 4x90mm Valved Rear Exhaust 527026 is the valved rear with its own tips.

What else do I need with them?

Supersprint sells these mufflers in a full kit: on the M340i behind its front section and the Center Pipes Kit 527013, or behind the factory particulate filter with the Sleeve Pipes 528555. On the ALPINA B3 they are part of the Supersprint B3 systems. Bulletproof Automotive supplies them on their own.

Do they fit the ALPINA B3?

Yes. Supersprint registers the Valved Rear Mufflers for the ALPINA B3 sedan and Touring with the particulate filter, both the 2020 to 2022 cars and the later cars from 2023, as well as the M340i. The B3 is a European-market car, and US owners are rare.

Do they fit the USA M340i?

Yes. Supersprint registers them for the USA-model G20 M340i and M340i xDrive with valve, and for the European sedan and Touring. The four-cylinder 330i uses the Supersprint 2x100mm Valved Rear Exhaust 525624 instead, which carries its own pair of 100mm tailpipes.

Supersprint lists the Valved Rear Mufflers as in stock at the factory, so they normally leave Mantova soon after the order is confirmed. Bulletproof Automotive lists them on backorder with notification and tells you when they are on the way.

Description

Supersprint Valved Rear Mufflers for G20 / G21 BMW M340i and ALPINA B3 [527004]

Supersprint’s Valved Rear Mufflers for G20 / G21 BMW M340i keep the factory tailpipes and change everything behind them, which makes them the most understated rear in the range and one of the most versatile. The right and left mufflers carry a valve for a quiet setting, and Supersprint registers them for the M340i sedan and Touring and for the ALPINA B3, a rare case of one Mantova rear serving both the BMW and its Buchloe cousin. Supersprint keeps them in stock. They suit an owner who wants a better voice without advertising it; anyone who wants Supersprint tips on show should choose the 4x90mm Valved Rear Exhaust.

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.
