Does the AWE Exhaust for Lexus GX 550 need a tune?

No. AWE marks this Exhaust for Lexus GX 550 as requiring no tune. It replaces the factory piping behind the emissions equipment and carries the AWE No CEL Guarantee, so the engine calibration stays as Lexus delivered it and nothing needs to be flashed after installation.

Will it drone on the highway?

AWE built the system around dual-phase 180 Technology because the GX 550 produces two frequencies that can drone at cruise. Tuned chambers cancel both, so you hear a fuller note when you accelerate and a quiet cabin at steady highway speed, with no added restriction.

Is it compatible with skid plates and an auxiliary fuel tank?

Yes, within what AWE has tested. The front pipes sit above the frame rails to leave room for skid plates, and AWE tested the fit with the Hellivue spare-mounted auxiliary tank. For any other rear tank or bumper, contact us before ordering and we will check with AWE.

Is the system legal in all 50 states?

AWE describes this 0FG system as 50-state emissions-compliant. It replaces only the piping behind the factory emissions equipment, and the BashGuard exits after the rear axle so the outlet location stays street legal. Local noise rules still apply, so check the regulations where you drive.

How is the Exhaust for Lexus GX 550 built?

Each Exhaust for Lexus GX 550 is made in-house by AWE in Pennsylvania from U.S.-sourced T304L stainless with a .065-inch wall. CNC mandrel bends keep the tube diameter consistent through every turn, and the system bolts in with no cutting, backed by the AWE Lifetime Warranty.

Description

AWE Tuning 0FG Exhaust for Lexus GX 550 3.4L with BashGuard Exit

AWE Tuning’s 0FG Exhaust for Lexus GX 550 3.4L with BashGuard Exit gives the twin-turbo V6 a fuller, more distinct voice while keeping the cabin calm on the highway and the underside clear on the trail. It is handcrafted from CNC mandrel-bent T304L stainless, bolts to the factory flanges with no cutting, and AWE lists it as 50-state emissions-compliant.

Dual-Phase 180 Technology

The GX 550 produces two frequencies that can drone at cruise. AWE’s patented 180 Technology routes both through tuned chambers and returns them out of phase so they cancel, while the main path stays straight-through.

Built for Clearance

Equal-length front pipes run above the frame rails, leaving room for skid plates. The BashGuard ends after the rear axle, removing low-hanging rear sections while keeping a street-legal exit, and an extra-thick stainless ring protects the outlet.

Auxiliary Fuel Tank Friendly

AWE physically tested the system with the Hellivue spare-mounted auxiliary fuel tank, so extended-range overland builds can keep it.

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.
