This typically includes the muffler, resonator, and piping. The purpose of a cat-back exhaust system is to improve exhaust flow and enhance the sound of the exhaust note. By reducing exhaust restrictions and back pressure, a cat-back exhaust can improve engine performance and increase horsepower and torque. The name \"cat-back\" refers to the fact that the catalytic converter, which is responsible for reducing harmful emissions, is not replaced or modified as part of this system.\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eProfessional Installation Is Highly Recommended!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/HvbazALsCuI?si=B7DOhjbSjT-9eY2B\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\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":50270413750410,"sku":"EXT-MD002_EXT-MP011","price":499.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/5548\/8394\/files\/cropped-_1992567_1.jpg?v=1790110614","url":"https:\/\/pistontwistin.org\/products\/2015-2021-subaru-wrx-sti-muffler-delete-quad-tips-cat-back-exhaust","provider":"Piston Twistin LLC","version":"1.0","type":"link"}
