The single side-exit layout keeps things simple and purposeful while adding a noticeable performance edge. From behind the wheel, the truck feels more eager to move, especially when accelerating from a stop or rolling into the throttle on the highway. The exhaust note is deeper and smoother, giving the Duramax a confident tone that stays comfortable for everyday driving. The polished oval side-exit tip adds a clean finishing touch that looks sharp without drawing too much attention. It is an ideal upgrade if you want improved drivability with a subtle performance look.\u003c\/p\u003e\n\u003ch4\u003eHigh Flow Design Built Around Factory Integration\u003c\/h4\u003e\n\u003cp\u003eThis DPF-back exhaust system replaces the factory muffler-equipped exhaust from the exhaust valve back to the tailpipe. It is constructed entirely from mandrel bent four-inch 304 stainless steel tubing for excellent durability and corrosion resistance. By eliminating the restrictive factory muffler, the system reduces exhaust back pressure to improve turbo efficiency and throttle response. The exhaust retains factory hanger locations and the factory exhaust valve to maintain proper operation and fitment. Installation does require cutting the factory exhaust, which should be considered before starting the job. Designed specifically for 2023-2025 GM 1500 Sierra and Silverado trucks with the 3.0L Duramax, this kit includes all necessary hardware and is backed by a limited lifetime warranty on the stainless exhaust components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2023, 2024, 2025 GM 1500 Sierra\/Silverado 3.0L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2023-2025 GM 1500 Duramax trucks\u003c\/li\u003e\n\u003cli\u003eFits Sierra and Silverado with 3.0L diesel\u003c\/li\u003e\n\u003cli\u003eSingle side-exit DPF-back exhaust configuration\u003c\/li\u003e\n\u003cli\u003eReplaces exhaust from exhaust valve back\u003c\/li\u003e\n\u003cli\u003eFactory exhaust valve remains fully functional\u003c\/li\u003e\n\u003cli\u003eFactory muffler is removed during installation\u003c\/li\u003e\n\u003cli\u003eCutting of the factory exhaust is required\u003c\/li\u003e\n\u003cli\u003eConstructed entirely from 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eUses factory hanger and mounting locations\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty on stainless exhaust system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0611\/8539\/2883\/files\/304-Stainless-Steel-DPF-Back-Performance-Exhaust-Kit-Single-Exit-Duramax_Install-Guide_R1225.pdf?v=1765384109\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":53861785927964,"sku":"PPE117150030","price":539.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/117150030-Exh-Kit-4-inch-DPF-Back-Single-Tip-GM-3-0L-Duramax-2023-2025_1.webp?v=1770159665","url":"https:\/\/www.alligatorperformance.com\/products\/ppe-117150030","provider":"Alligator Performance","version":"1.0","type":"link"}
