From the first startup, the freer flowing design delivers a deeper, more confident exhaust note without being overbearing on the highway. Additionally, reducing back pressure helps the turbo work more efficiently, which can translate into improved throttle response and better fuel economy during daily driving or long hauls. The system removes the restrictive factory muffler while retaining the factory exhaust valve, so you keep OEM functionality with noticeably improved performance. Built entirely from high grade 304 stainless steel, this exhaust is made to handle harsh weather, road salt, and hard miles without sacrificing appearance. What’s more, the black coated side exit tip adds a clean, aggressive finish that looks right at home on a modern Sierra or Silverado.\u003c\/p\u003e\n\u003ch4\u003eEngineered For Efficiency Durability And Factory Level Fitment\u003c\/h4\u003e\n\u003cp\u003eThis DPF-back exhaust kit is constructed using full 4-inch mandrel bent 304 stainless steel tubing to ensure consistent airflow from the exhaust valve back to the tailpipe. The smoother bends and larger diameter help reduce restriction at the manifolds, supporting quicker turbo response and more efficient exhaust gas flow. Furthermore, the system is designed to eliminate the factory muffler while utilizing all factory hanger locations, maintaining proper clearance and alignment under the truck. PPE includes all required 304 stainless steel clamps and hardware, allowing for a straightforward installation once the factory exhaust is cut as required. The 5.5-inch oval side exit tip features a durable black ceramic coating that resists discoloration and heat cycling. Backed by a limited lifetime warranty on the stainless system, this exhaust is built to deliver long term performance and confidence for 2023-2025 GM 1500 Duramax owners.\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\u003eThis is a DPF-back exhaust system and does not affect emissions equipment.\u003c\/li\u003e\n\u003cli\u003eFactory exhaust valve is retained for proper OEM functionality.\u003c\/li\u003e\n\u003cli\u003eInstallation requires cutting the factory exhaust system.\u003c\/li\u003e\n\u003cli\u003eConstructed entirely from 304 stainless steel, not 409 stainless.\u003c\/li\u003e\n\u003cli\u003eSystem replaces the factory muffler from valve to tailpipe.\u003c\/li\u003e\n\u003cli\u003eDesigned to reduce back pressure and support turbo efficiency.\u003c\/li\u003e\n\u003cli\u003eUses all factory hanger locations for proper fitment.\u003c\/li\u003e\n\u003cli\u003eIncludes all necessary clamps and installation hardware.\u003c\/li\u003e\n\u003cli\u003eBlack ceramic coated tip carries a one-year finish warranty.\u003c\/li\u003e\n\u003cli\u003eStainless exhaust components are backed by a limited lifetime warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" 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\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":53861980012828,"sku":"PPE117153020","price":539.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/117153020-Exh-Kit-4-inch-DPF-Back-Single-Tip-GM-3-0L-Duramax-2023-2025-Pol-Blk_1.webp?v=1770163305","url":"https:\/\/www.alligatorperformance.com\/products\/ppe-117153020","provider":"Alligator Performance","version":"1.0","type":"link"}
