How does the AWE SwitchPath Catback Exhaust control the valves on the F90 BMW M5, and does it need an aftermarket remote?

No remote is required. The SwitchPath retains all of the M5's factory valve behavior, responding to drive mode changes and the factory exhaust button on the center console without any additional hardware. In Comfort mode the valves close and the system produces a refined, full-bodied S63 tone with interior acoustics close to stock at cruise. In Sport and Sport+ mode the valves open, uncorking the twin-turbo V8 with a powerful, aggressive note. AWE describes the valve-closed character as good enough that many owners leave it there all the time.

What is the difference between the AWE SwitchPath Catback and the SwitchPath Axleback for the F90 M5?

The Catback replaces the full system from the downpipes back, including a precision-engineered X-pipe and valved rear sections, delivering the full performance and sound package with a 17 lb weight savings over stock. The Axleback retains the M5's factory mid-section and picks up right at the rear axle, swapping only the rear muffler sections for the SwitchPath valved configuration. The Axleback is a more cost-effective entry point into the system; the Catback is the complete build. Both retain factory valve behavior in full.

What are the peak versus maximum gains for the AWE SwitchPath Catback on the F90 M5?

The AWE SwitchPath Catback delivers peak gains of 4hp and 4ft-lb of torque at the wheels, with maximum gains of 22hp and 18ft-lb. The peak figures represent gains at the most responsive point in the power curve; the maximum figures represent the highest recorded gains at a specific RPM point across the full dyno pull. Both are at-the-wheel figures on the S63 twin-turbo V8 with the Catback system installed.

What is the difference between the AWE SwitchPath and Track Edition for the F90 M5?

Both share the same dual 3" T304L stainless steel construction and precision-engineered X-pipe. The SwitchPath uses valved rear sections that respond to the factory drive modes and exhaust button, giving you a composed tone with valves closed and a fully uncorked S63 with valves open. The Track Edition removes the valves entirely for full-time, unfiltered volume and a 21 lb weight savings compared to the SwitchPath's 17 lb savings. The Track Edition is known to get rowdy at all speeds and cannot be returned based on sound preference; the SwitchPath is the correct choice for drivers who want both ends of the spectrum accessible from inside the cabin.

Description

AWE Tuning M5 SwitchPath Cat-Back Exhaust w/ Black Diamond Tips for F90 BMW M5

The AWE Tuning M5 SwitchPath Cat-Back Exhaust with Black Diamond Tips is designed, engineered, and manufactured entirely in-house at AWE, and it shows in every detail. The catback installs as a pure bolt-on with no cutting or modification required, and AWE backs the fitment with their No Check Engine Light guarantee so there are no surprises after installation. Construction is dual 3″ CNC mandrel-bent T304L stainless steel with .065″ wall thickness, sourced in the U.S., and the straight-through design keeps things clean and unrestricted without unnecessary complexity.

SwitchPath Edition

The AWE SwitchPath™ Exhaust is offered as a full catback or axleback system, and it handles both ends of the spectrum well; at cruising speeds it stays quiet and unobtrusive, but get into the throttle and the 4.4T twin-turbo comes alive with a sound that fits the car. The system is fully valved and works with the factory valve logic, so the M5’s drive modes control it exactly as you’d expect with no extra hardware or workarounds. On the performance side, you’re looking at peak gains of 4 hp and 4 ft-lbs of torque, max gains of 22 hp and 18 ft-lbs at the wheels, and a 17lbs drop in weight over the stock system.

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.
