It typically includes the muffler and exhaust pipes that extend from the rear axle to the back of the vehicle. Axle back exhaust systems are designed to improve the sound and performance of a vehicle by increasing exhaust flow and reducing restrictions. They are relatively easy to install and do not require any modifications to the vehicle's exhaust system before the rear axle.

Axle back exhaust systems are designed to improve the sound and performance of a vehicle by increasing exhaust flow and reducing restrictions. They are relatively easy to install and do not require any modifications to the vehicle's exhaust system before the rear axle. Axle back exhaust systems are a popular choice among car enthusiasts who want to enhance the sound and appearance of their vehicles without modifying the entire exhaust system.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProfessional Installation Is Highly Recommended!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/Al_2kz4-u0Q?si=3OTX1N-VST1btzfo\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/4009\/6449\/files\/EOS_480x480.jpg?v=1680043242\" alt=\"\"\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"EOS Exhaust","offers":[{"title":"Default Title","offer_id":48911783592022,"sku":"EXT-MD119","price":249.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0765\/9195\/6054\/files\/CP1NW_c55b06b2-fdbd-4bac-a6dc-d3630ac2fa9a.jpg?v=1790118910"},{"product_id":"2022-present-subaru-wrx-sti-resonated-mid-pipe","title":"2022-Present Subaru WRX STi Resonated Mid Pipe","description":"\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eCOMPATIBILITY:\u003c\/strong\u003e 2022-Present Subaru WRX\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eMATERIAL:\u003c\/strong\u003e T-304 Stainless Steel\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eSURFACE FINISH:\u003c\/strong\u003e Anodized Silver\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eTYPE: \u003c\/strong\u003eResonated Mid Pipe\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong\u003eMID PIPE DIAMETER: \u003c\/strong\u003e3 Inch Split to 2.5 Inch Piping Mandrel Bent Piping\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eImproved Performance: The stock mid-pipe of the WRX can restrict exhaust flow, which negatively affects performance.
