What is the difference between the Supersprint Resonated Front X-Pipe and the Non-Resonated version?

The Resonated Front X-Pipe carries small resonators in each pipe ahead of the X, which reduce drone at a steady cruise. The Non-Resonated version, part number 529252, uses straight pipes and is louder. Both replace the factory front and central mufflers.

Does it fit a European M5 with the particulate filter?

No. Supersprint registers this front section for the USA-model G90 M5 sedan and G99 M5 Touring only. The European cars with the particulate filter take a different Supersprint front section that is not sold through Bulletproof Automotive, so check the specification of the car before ordering.

Does it fit the M5 Touring?

Yes. Supersprint registers the same part number for the USA-model G99 M5 Touring as for the G90 sedan, so one code covers both body styles. The Touring needs no different front section, and fitment is the same on both cars.

What does the X-pipe do?

The X-pipe joins the right and left pipes of the V8 at a crossover, so the exhaust pulses from both banks meet and balance before the rear of the car. On a V8 that crossover changes the character of the sound compared with a system that keeps both banks separate all the way back.

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.

Supersprint Resonated Front X-Pipe for G90 / G99 BMW M5

Supersprint’s Resonated Front X-Pipe for G90 / G99 BMW M5 replaces the factory front and central mufflers with a right and left pair of stainless pipes that meet in an X-pipe before the axle-back section. This version carries two small resonators in the pipework ahead of the X, visible in the photograph, which take the edge off drone at a steady cruise. It is the one to choose for a car that covers long highway miles; the Non-Resonated version gives up that refinement for a louder, more open sound. Supersprint registers it for the USA-model M5 sedan and Touring only, so it is the front section for a US car.

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.
