From the first drive, the truck feels more eager to accelerate, especially when rolling into the throttle on the highway or climbing long grades. The sound takes on a deeper, more confident tone that lets you know the engine is breathing easier, yet it stays controlled for daily driving. Raw stainless tubing paired with polished quad tips gives the rear of the truck a clean performance look that feels intentional and well finished. Because the factory exhaust valve is retained, the system remains quiet when cruising and opens up naturally under load. It is a well balanced upgrade that improves response, sound, and appearance all at once.\u003c\/p\u003e\n\u003ch4\u003eEngineered For Flow Efficiency And Long Term Durability\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 corrosion resistance and long service life. By eliminating the restrictive factory muffler, the system reduces exhaust back pressure to improve turbo efficiency and engine response. The exhaust retains factory mounting locations and the factory exhaust valve to maintain proper operation and fitment. Installation does require cutting the factory exhaust, which should be considered before installation. Designed specifically for 2023-2025 GM 1500 Sierra and Silverado trucks with the 3.0L Duramax, this kit includes 304 stainless steel clamps and is backed by a limited lifetime warranty on the stainless exhaust components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e2023, 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\u003eDPF-back system replaces exhaust after exhaust valve\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\u003eIncludes 304 stainless steel clamps\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty on stainless exhaust components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0611\/8539\/2883\/files\/11716X0XX-Stainless-Steel-DPF-Back-Performance-Dual-Exhaust-Kit_Install-Guide_R1025.pdf?v=1761095075\" 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":53861614485788,"sku":"PPE117160030","price":1169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/117160020-1.webp?v=1770156400","url":"https:\/\/www.alligatorperformance.com\/products\/ppe-117160030","provider":"Alligator Performance","version":"1.0","type":"link"}
