{"product_id":"high-flow-exhaust-manifold-and-up-pipe-kit-6-6l-duramax","title":"High-Flow Exhaust Manifold and Up-Pipe Kit, 6.6L Duramax","description":"The PPE High-Flow Exhaust Manifold and Up-Pipe Kit is a comprehensive performance upgrade engineered to address exhaust back-pressure issues in 2007.5-2010 GM 6.6L Duramax trucks. The manifolds are cast from high-sil moly iron for durability, while the included up-pipes feature an increased inner diameter and aircraft-grade 304 stainless steel construction with internal sleeving to promote smooth, laminar exhaust flow.\n\nThese kits are 50-state emissions legal under E.O. D-701-34. The up-pipes utilize a 2-inch outside diameter with 11-gauge, 0.120-inch wall thickness. To facilitate monitoring, the manifolds include pre-drilled and tapped 1\/8\" NPT bosses for EGT sensors. Optional ceramic coating is available for the manifolds, which creates a thermal barrier to further reduce surface temperatures and protect against road-borne corrosion.\n\nInstallation requires specific considerations for certain vehicle configurations. Note that the LML model requires a modification to the upper control arm bushing heat shield for proper clearance. Additionally, the factory downpipe from 2001-2004 LB7 models does not fit these aftermarket manifolds and up-pipes. For optimal results, the manufacturer recommends completing the exhaust system with the PPE 3-inch 304 stainless steel downpipe.","brand":"PPE","offers":[{"title":"Default Title","offer_id":52663322968376,"sku":"PPE-1161118-P","price":1292.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687527845.jpg?v=1784325941","url":"https:\/\/store.motormia.co\/products\/high-flow-exhaust-manifold-and-up-pipe-kit-6-6l-duramax","provider":"MOTORMIA","version":"1.0","type":"link"}
