This system ditches the factory muffler completely, unlocking that bold, aggressive diesel tone you’ve been missing. Whether you’re daily driving or towing heavy loads, the deep rumble will make your truck sound as strong as it feels. And it doesn’t just sound good, the 5-inch stainless tubing helps reduce backpressure, improving throttle response and turbo spool, especially on tuned setups. The polished 6-inch tip adds the perfect finishing touch with an intercooled design that keeps surface temps in check and brings a clean, custom look to the rear of your truck. You won’t need a lift or a welder to get it installed either, thanks to the clamp-on design that bolts up easily using standard hand tools. This is a system built for real-world use, built for diesel guys who want performance they can hear and feel.\u003c\/p\u003e\n\u003ch4\u003eBuilt For Maximum Flow Without Sacrificing Compliance\u003c\/h4\u003e\n\u003cp\u003eThe MagnaFlow 17870 Pro Series is designed for Duramax owners who want all-out flow and sound without interfering with emissions systems. This DPF-back exhaust system fits 2007–2023 Silverado and Sierra 2500HD and 3500HD models and uses 5-inch mandrel-bent tubing to keep exhaust velocity high and restriction low. The lack of a muffler allows for the most aggressive tone in MagnaFlow’s DPF-back lineup, while the system’s layout ensures compatibility with factory emissions components. Made from 409 stainless steel, it offers solid resistance to rust and corrosion in harsh driving conditions. The tip is a 13-inch long, rolled-edge stainless steel piece with a 6-inch diameter and internal cooling fins to help control surface heat at the outlet. It’s a clean, high-flow design that balances performance and practicality, delivering audible and measurable gains without triggering issues with emissions compliance. Everything bolts in place using existing factory mounting points, making it a solid choice for DIY installs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 GM Silverado\/Sierra 2500HD\/3500HD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes all clamps and hardware for installation\u003c\/li\u003e\n\u003cli\u003eDesigned to retain all factory emissions equipment\u003c\/li\u003e\n\u003cli\u003eDPF-back system is emissions compliant in all states\u003c\/li\u003e\n\u003cli\u003eClamp-on system does not require cutting or welding\u003c\/li\u003e\n\u003cli\u003eMuffler delete design may be too loud for some users\u003c\/li\u003e\n\u003cli\u003ePolished intercooled tip helps lower surface temps\u003c\/li\u003e\n\u003cli\u003eTip features a rolled edge and angle-cut design\u003c\/li\u003e\n\u003cli\u003eBuilt from corrosion-resistant 409 stainless steel\u003c\/li\u003e\n\u003cli\u003eDesigned to fit 2007–2023 Silverado and Sierra HD models\u003c\/li\u003e\n\u003cli\u003eDoes not fit cab \u0026amp; chassis or commercial fleet trucks\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Magnaflow Exhaust Products","offers":[{"title":"Default Title","offer_id":49526687826204,"sku":"MFL17870","price":839.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/ef56ddb9777cb48110cc2919076cb270_750x_8c0a3214-b83c-479a-8e29-e8cd371ac15e.webp?v=1759352411"},{"product_id":"mbrp-s5093al-cat-back-performance-exhaust-system","title":"MBRP S5093AL 4\" inch Cat Back Exhaust System Single Side Exit | 2020-2025 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax V8","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4-inch aluminized steel cat-back system\u003c\/li\u003e\n\u003cli\u003eSingle side exit with 5-inch tip included\u003c\/li\u003e\n\u003cli\u003eDyno-tested for proven performance gains\u003c\/li\u003e\n\u003cli\u003eImproves exhaust flow and reduces backpressure\u003c\/li\u003e\n\u003cli\u003eEnhanced throttle response and fuel efficiency\u003c\/li\u003e\n\u003cli\u003eDeep, aggressive sound without cabin drone\u003c\/li\u003e\n\u003cli\u003eMandrel-bent tubing for smoother flow\u003c\/li\u003e\n\u003cli\u003eBolt-on design for easy installation\u003c\/li\u003e\n\u003cli\u003eUses OEM-style hangers and includes hardware\u003c\/li\u003e\n\u003cli\u003eThree-year warranty on aluminized steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eHigh-Performance Exhaust System for GM 6.6L Duramax\u003c\/h4\u003e\n\u003cp\u003eIf you’re looking to give your 2020–2025 Silverado or Sierra HD with the 6.6L gas V8 a little more muscle, both in sound and performance, the MBRP 4-inch Cat-Back Exhaust System from the Installer Series is a solid choice that delivers results without overcomplicating things.

Designed for 2007.5–2025 Silverado and Sierra 2500HD\/3500HD trucks with the 6.6L Duramax, this system brings out that deep, powerful tone diesel owners love, without touching emissions components. The first thing you’ll notice is the sound. It’s not obnoxious or over the top, but it’s bold, throaty, and unmistakably diesel. MagnaFlow tuned this system to enhance your truck’s natural exhaust note, so every start-up, gear change, and throttle input feels a little more alive. What's more, the 5-inch diameter improves exhaust flow compared to the stock system, helping reduce backpressure and supporting performance gains, especially on tuned or heavily worked trucks. At the tail end, the system features a black intercooled tip.\u003c\/p\u003e\n\u003ch4\u003eHigh-Quality Construction with Bolt-On Install\u003c\/h4\u003e\n\u003cp\u003eFrom a construction standpoint, it’s built to last. The entire system is made from durable stainless steel and finished in a high-temp black powder coat that resists corrosion and adds a stealthy, aggressive look. That finish doesn’t just look good, it also helps manage heat and protect the system in harsh conditions, whether you're towing, working, or hitting the trails. Best of all, installation is straightforward thanks to MagnaFlow’s use of 3D scanning to ensure perfect fitment. This system bolts directly to your factory DPF flange and includes all the hardware you’ll need for a clean, do-it-yourself install. There’s no cutting or welding, and everything lines up with OEM mounting points for a hassle-free experience in the garage or driveway.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 2007.5, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLifetime construction warranty, 1-year finish warranty.\u003c\/li\u003e\n\u003cli\u003eBlack powder coat may chip over time with exposure.\u003c\/li\u003e\n\u003cli\u003eIntercooled tip reduces surface heat at exhaust exit.\u003c\/li\u003e\n\u003cli\u003eDPF-back design keeps emissions equipment untouched.\u003c\/li\u003e\n\u003cli\u003eTuned for deep sound outside, mild tone inside the cab.\u003c\/li\u003e\n\u003cli\u003eBolts to factory DPF flange, no cutting or welding needed.\u003c\/li\u003e\n\u003cli\u003eMandrel-bent tubing improves flow and reduces backpressure.\u003c\/li\u003e\n\u003cli\u003eMay not fit cab \u0026amp; chassis or non-standard configurations.\u003c\/li\u003e\n\u003cli\u003eFinish may fade faster in harsh climates or off-road use.\u003c\/li\u003e\n\u003cli\u003eInstall is DIY-friendly but basic tools and skill are required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Magnaflow Exhaust Products","offers":[{"title":"Default Title","offer_id":49527319560476,"sku":"MFL17072","price":1043.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/17072_1.jpg?v=1722344778"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/collections\/GM_Duramax_Single-Exit_Kit_Thumb_1.jpg?v=1728499254","url":"https:\/\/www.alligatorperformance.com\/collections\/2020-2026-gm-duramax-66l-l5p-single-exit-dpf-back-kits.oembed","provider":"Alligator Performance","version":"1.0","type":"link"}
