Why should I choose the non-resonated Touring Edition over the resonated version for my G2X M340i or M440i?

AWE's own recommendation, confirmed across their product page and multiple authorized retailers, is straightforward; go non-resonated if you are running the factory downpipe. The non-resonated mid-pipe sections deliver a fuller, more immediate B58 tone with slightly more presence than the resonated version, while AWE's patented 180 Technology® at the rear still handles drone suppression for a clean highway cruise. If your car already has an aftermarket downpipe installed, the resonated version is the better pairing; combining a freer-flowing aftermarket downpipe with non-resonated mid-sections can introduce rasp that the resonated mid-pipes control.

What happens if I start with the non-resonated version and later upgrade my downpipe on the G2X M340i or M440i?

It is a simple swap. AWE offers a Resonator Conversion Kit specifically for this scenario; when you go aftermarket on the downpipe, you swap the non-resonated mid-pipe sections for resonated ones without touching the rest of the system. The stamped stainless steel merge, dual 3" piping, and rear 180 Technology® sections all stay in place. AWE built the G2X exhaust suite to be fully modular precisely for builds that evolve over time.

Does the AWE Non-Resonated Touring Edition Exhaust fit G2X GranCoupe models of the M340i or M440i?

No. AWE's exhaust suite for the G2X M340i and M440i is not approved for GranCoupe variants. Confirmed fitment covers the G20 M340i sedan and M340i xDrive, and the G22 M440i coupe and M440i xDrive coupe. If you own a GranCoupe body style, this system is not the right fit.

Can I convert the AWE Non-Resonated Touring Edition to the Track Edition later on my G2X M340i or M440i?

Yes. AWE built the G2X exhaust suite with full modularity; conversions between Touring and Track Editions, resonated and non-resonated mid-sections, and OE to quad-tip configurations are all handled through AWE conversion kits without replacing the full system. The Track Edition removes the rear 180 Technology® resonators for full-time, unfiltered B58 tone and delivers an 11 lb weight savings over stock. Keep in mind the Track Edition is known to get rowdy at all speeds and cannot be returned based on sound preference.

AWE Tuning Non-Resonated Touring Edition Exhaust w/ Quad Diamond Black Tips for G2x BMW M340i & M440i

AWE M340i touring exhaust in non-resonated form is handcrafted from 3″ CNC mandrel-bent, U.S.-made .065″ wall T304L stainless steel and delivers 65% more flow than stock, making it ready to support big power builds down the road. AWE’s patented 180 Technology keeps drone out of the cabin while preserving the full B58 tone, and the non-resonated configuration adds a bit more presence compared to the resonated version for drivers who want that extra edge. A mid-pipe inlet adapter is included for compatibility with both stock and aftermarket downpipes with 80mm outlets; the system bolts on directly with no cutting required, and it finishes with quad 102mm double-walled slash-cut tips in diamond black. On stock software, expect max gains of 16hp and 12ft-lb of torque at the wheels.

Touring Edition Exhaust

The AWE Touring Edition Exhaust is a dual 3″ T304L stainless steel, downpipe-back system built to deliver straight-pipe performance without making the car unlivable day-to-day. A stamped stainless steel merge section up front flows the equivalent of dual 3″ off the downpipe, pushing a 65% increase in flow over stock and leaving the setup ready for aftermarket downpipes down the road. From there, the exhaust splits into true dual 3″ piping and finishes with AWE’s patented 180 Technology, keeping drone out of the cabin while holding onto the full-bodied, turbocharged B58 tone throughout.

What is 180 Technology?

AWE acoustic engineers determine the size and placement of each port and chamber based on the sound targets for that specific vehicle. Sound waves travel with the exhaust gases, bounce off the reflection chamber walls, and return to the main flow at a point controlled entirely by those dimensions. That timing is the key; when it lands right, the returning wave runs 180 degrees out of phase with the problem frequencies and cancels them out before they ever leave the 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.
