This listing is built around aFe POWER part number \u003cstrong\u003e49-36056\u003c\/strong\u003e for the 2010–2021 Lexus GX460 4.6L V8 – MPN 49-36056.\u003c\/p\u003e\u003cp\u003eaFe's performance exhaust systems are engineered around tubing diameter, bend quality, merge transitions, muffler\/resonator strategy, hanger placement and tip configuration. Those details determine not only restriction but also tone, volume, clearance and how well the system integrates with the chassis.\u003c\/p\u003e\u003ch3\u003eWhat This Means on the Car\u003c\/h3\u003e\u003cp\u003eAn exhaust should be selected for the complete use case. Larger tubing and lower restriction can support additional airflow, but sound character is equally important on a street car. Axle-back systems primarily change the rear section and sound; cat-back and larger upstream systems address more of the exhaust path.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Part Numbers\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e 2010–2021 Lexus GX460 4.6L V8 – MPN 49-36056\u003cbr\u003e\u003cstrong\u003eaFe POWER part number:\u003c\/strong\u003e 49-36056\u003c\/p\u003e\u003cp\u003eFitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.\u003c\/p\u003e\u003ch3\u003eLegacy Racing Enthusiast Perspective\u003c\/h3\u003e\u003cp\u003eWe recommend deciding first how much additional sound you actually want, then choosing the system architecture. For track-capable street cars, we also consider local sound limits and whether a muffler\/resonator configuration leaves enough margin for future engine modifications. On the 2010–2021 Lexus GX460 4.6L V8 – MPN 49-36056, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.\u003c\/p\u003e","brand":"Legacy Racing","offers":[{"title":"Default Title","offer_id":50260709671162,"sku":"AFE49-36056","price":884.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0325\/6352\/7739\/files\/d138cccb68702255d3a12b454188a3d1.jpg?v=1783037423","url":"https:\/\/lgcracing.com\/products\/afe-vulcan-series-2-5-304ss-cat-back-exhaust-10-21-lexus-gx460-v8-4-6l","provider":"Legacy Racing","version":"1.0","type":"link"}
