{"product_id":"5inch-full-exhaust-duramax-2011-2016","title":"5\" Down Pipe-Back Full Exhaust Delete | GM\/Chevy 6.6 Duramax 2011-2016","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan data-sheets-root=\"1\"\u003eThe 5\" Downpipe-Back Delete Pipe for 2011–2016 LML Duramax removes the Diesel Particulate Filter (DPF) and catalytic converter (CAT) from your Silverado 2500HD\/3500HD or Sierra 2500HD\/3500HD. It's our best-selling Duramax 5\" full exhaust, built from high-quality T-409 stainless steel with OEM-style hangers and clamps for an easy, factory-style install. Free shipping is included.\u003cbr\u003e\u003cbr\u003eThat 5\" diameter moves more exhaust volume than a 4\" pipe — less restriction at high-load RPM, faster turbo spool under heavy towing, and a more aggressive tone. The system runs from the downpipe back and replaces the OEM DPF and CAT sections with a wider, free-flowing path. With regen cycles and DPF backpressure gone, most owners feel the throttle response improve right away.\u003cbr\u003e\u003cbr\u003eIn the box you get the 5\" T-409 stainless full exhaust, OEM-style hangers and clamps, and a step-by-step installation guide. It fits all cab and box lengths on the pickup models but does not fit Cab \u0026amp; Chassis trucks. One important note for 2015: early 2015 trucks use a V-Band clamp at the downpipe, while 2015.5 trucks use a 3-bolt flange — check your connection before ordering.\u003cbr\u003e\u003cbr\u003eYou'll need a compatible delete tune so the ECM doesn't throw DPF codes; call (888) 830-2588 to pair the right LML tuner. Final sale on exhaust — damaged or incorrect parts get replaced at no cost.\u003cbr\u003e\u003cbr\u003eFor off-road\/competition use only.\u003c\/span\u003e\u003c\/p\u003e","brand":"thedieseldudes","offers":[{"title":"2011-2015 \/ No Muffler","offer_id":40929723678764,"sku":"DW-5EXH-CHEV-1115","price":899.0,"currency_code":"USD","in_stock":true},{"title":"2011-2015 \/ Add Muffler","offer_id":40929723711532,"sku":"DW-5MEXH-CHEV-1115","price":969.0,"currency_code":"USD","in_stock":true},{"title":"2015.5-2016 \/ No Muffler","offer_id":40929723744300,"sku":"DW-5EXH-CHEV-1516","price":899.0,"currency_code":"USD","in_stock":true},{"title":"2015.5-2016 \/ Add Muffler","offer_id":40929723777068,"sku":"DW-5MEXH-CHEV-1516","price":969.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/6163\/9212\/products\/95.png?v=1674746548","url":"https:\/\/thedieseldudes.ca\/products\/5inch-full-exhaust-duramax-2011-2016","provider":"thedieseldudes","version":"1.0","type":"link"}
