From the driver’s seat, the truck feels more eager to accelerate, especially during highway passing and steady towing pulls. The exhaust note gains a deeper, smoother tone that adds character without becoming intrusive on long drives. Polished stainless tubing and quad polished tips give the rear of your Sierra or Silverado a clean, premium look that stands out in all the right ways. Because the factory exhaust valve is retained, the system stays composed during cruising and opens up naturally when you lean into the throttle. It is an upgrade that improves how the truck drives and looks without sacrificing daily comfort.\u003c\/p\u003e\n\u003ch4\u003eEngineered For Efficient Flow 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 built entirely from mandrel bent four-inch 304 stainless steel tubing for excellent corrosion resistance and long service life. The free-flowing design reduces exhaust back pressure, helping improve turbo efficiency, throttle response, and overall engine performance. Factory hanger locations are retained to ensure proper fitment and alignment once installed. 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 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\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\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":53861734973724,"sku":"PPE117163030","price":1169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/117163030-1.webp?v=1770158308","url":"https:\/\/www.alligatorperformance.com\/products\/ppe-117163030","provider":"Alligator Performance","version":"1.0","type":"link"}
