What do I need with the Supersprint 4x90mm Rear Exhaust for G29?

Supersprint lists the 4x90mm Rear Exhaust for G29 in its M40i system behind a front section, pipes or Sport Cats, and the Center Pipes Kit 525813. It does not state that the rear must be installed with them, so ask Bulletproof Automotive before fitting it to the factory mid section.

Does it have a valve?

No. Supersprint lists this rear without a valve and as the alternative to its 4x90mm Valved Rear Exhaust 525826. It is at full voice all of the time. Owners who want a quiet setting for early starts or long highway runs should choose the valved rear.

Does it fit the USA Z4 M40i?

Yes. Supersprint registers it for the USA-model Z4 M40i as well as the European car with and without the particulate filter. It does not fit the four-cylinder Z4 or the GR Supra, which take different Supersprint rears. Check the engine before ordering.

What tips does it have?

Supersprint lists it as Right OO90 and Left OO90, which is two round 90mm tailpipes on each side, four in all. They are fitted to the mufflers and made for the factory M40i rear bumper, so the car needs no bodywork changes.

Supersprint lists this rear as in stock at the factory, so it normally leaves Mantova soon after the order is confirmed. Bulletproof Automotive lists it on backorder with notification and tells you as soon as it is on the way.

Supersprint 4x90mm Rear Exhaust for G29 BMW Z4 M40i [049326]

Supersprint’s 4x90mm Rear Exhaust for G29 BMW Z4 M40i gives the fastest Z4 the rear it deserves: a right and left rear with two 90mm Supersprint tailpipes on each side, made for the factory bumper, and no valve in the way. Supersprint lists it as the alternative to its valved M40i rear and registers it for the USA and European car, with and without the particulate filter. It is one of the Supersprint parts held in stock. It is the purer of the two M40i rears, and the one for an owner who wants the B58 heard every time the roof comes down; for a car that must also be quiet, the valved rear is the better buy.

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.
