This listing is built around aFe POWER part numbers \u003cstrong\u003e49-36080-P, 49-36080-B\u003c\/strong\u003e for the 2025 Toyota 4 Runner 304.\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\u003eConfiguration Guide\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eTip Finish:\u003c\/strong\u003e Polished, Black.

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 2025 Toyota 4 Runner 304, 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":"Polished","offer_id":50260521582842,"sku":"AFE49-36080-P","price":1153.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":50260521615610,"sku":"AFE49-36080-B","price":1209.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0325\/6352\/7739\/files\/6045b6e7eb25c969137c33e27a5a4be9L_eabb6fed-43e5-4d86-acb3-384d4ea284d7.jpg?v=1783037433","url":"https:\/\/lgcracing.com\/products\/afe-2025-toyota-4-runner-2-5-to-3-ss-304-cat-back-exhaust-w","provider":"Legacy Racing","version":"1.0","type":"link"}
