The AWE 0FG Exhaust for the Lexus GX 550 is a 50-state emissions-compliant catback system featuring equal-length front pipes, dual-phase 180 Technology, and high-clearance BashGuard. Handcrafted in-house from CNC mandrel-bent 3 and 2.5 U.S.-sourced .065-wall T304L stainless steel, the 0FG is engineered for signature sound, maximum highway comfort, and serious clearance. Factory-matched flanges make installation direct and precise. No cutting required.The GX 550 presents more than one frequency capable of producing unwanted in-cabin drone. The solution is dual-phase 180 Technology. AWEs patented drone-canceling technology targets the two problematic frequencies generated under cruising conditions and routes them through precisely engineered chambers. By controlling the size and location of the ports and chambers, we control when the reflected sound waves rejoin the main exhaust flow. That timing creates a 180-degree out-of-phase sound wave that cancels the problematic frequencies. The result: full-bodied tone when youre on it, maximum comfort when youre not.Equal-length front pipes ensure exhaust pulses from each bank travel the same distance before converging downstream. The balanced geometry shapes the GX 550s twin-turbo V6 into a smooth, distinct exhaust note while providing the foundation for the systems straight-through architecture. Equal length by design. Signature sound by result.The 0FGs front pipes are routed above the GX 550s frame rails, preserving valuable underbody clearance and compatibility with skid plate systems. Out back, the high-clearance BashGuard terminates after the rear axle, eliminating low-hanging rear sections while maintaining a street-legal exit location. An extra-thick reinforced stainless steel ring surrounds the BashGuard outlet, built to handle the abuse that comes with putting the GX 550 where it belongs.More range without sacrificing the exhaust. The 0FG Exhaust is engineered to maintain compatibility with spare-mounted auxiliary fuel tank configurations and has been physically tested with the Hellivue auxiliary tank.Every AWE 0FG Exhaust for the Lexus GX 550 is engineered, designed, and manufactured in-house from U.S.-sourced .065-wall T304L stainless steel. CNC mandrel bends maintain consistent cross-sectional area throughout the system, while the clean, straight-through design maximizes flow and durability.The AWE 0FG Exhaust is a 50-state emissions-compliant catback system that retains the GX 550s factory emissions equipment.50-state emissions-compliant catback with rugged high-clearance BashGuardDual-phase 180 Technology, AWEs patented drone-canceling solution, kills two frequencies responsible for in-cabin drone on the GX 550 resulting in max comfort on the highwayEqual-length front pipes for a signature exhaust noteFactory-matched flanges for ease of installationSkid plate friendly: front pipes engineered above the frame rails to preserve clearance for skid plate systemsSpare-mounted auxiliary fuel tank friendly (tested with Hellivue aux tank)High-clearance BashGuard ends after the rear axle making it street-legal, and features an extra thick reinforced stainless ring on the outlet, built for bashingHandcrafted from CNC mandrel-bent 3″ & 2.5″ U.S.-sourced .065 wall T304L stainless steelLess is more: clean, straight-through design maximizes performanceDirect bolt-on, no cutting requiredManufactured in-house at AWEAWE No CEL GuaranteeAWE Perfect Fitment GuaranteeAWE Lifetime WarrantyFits:Lexus GX550 (2024+)
