From the first drive, the engine feels more responsive, especially when pulling onto the highway or easing into the throttle around town. The sound is deeper and smoother, adding character without becoming loud or tiring on long trips. The single side-exit layout keeps the look clean and practical, while the polished oval tip and polished tubing add a premium finish. Retaining the factory exhaust valve helps maintain a calm tone during cruising and opens things up naturally when needed. It is an upgrade that makes the truck feel better to drive while giving it a subtle but upscale performance look.\u003c\/p\u003e\n\u003ch4\u003eHigh Flow Stainless Construction With Factory Friendly Design\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 resistance to corrosion. Removing the restrictive factory muffler helps reduce exhaust back pressure, improving turbo efficiency and overall engine response. The system uses factory hanger locations and retains the factory exhaust valve to ensure proper fitment and operation. Installation does require cutting the factory exhaust, which should be considered before starting the install. Designed specifically for 2023-2025 GM 1500 Sierra and Silverado trucks equipped with the 3.0L Duramax, this kit includes all required 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\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":53861973754140,"sku":"PPE117153030","price":539.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/117153030-Exh-Kit-4-inch-DPF-Back-Single-Tip-GM-3-0L-Duramax-2023-2025_1.webp?v=1770162750","url":"https:\/\/www.alligatorperformance.com\/products\/ppe-117153030","provider":"Alligator Performance","version":"1.0","type":"link"}
