D-701-34). GM 6.6L Duramax High-Flow Exhaust Manifolds and Up-Pipes Kits\u003c\/p\u003e\u003cp\u003ePPE High-Flow Manifolds are made from cast, high-sil moly. The PPE Up-Pipe bellows are internally sleeved, made from aircraft-grade 304 stainless steel, and designed with increased inner diameter for higher flow.\u003c\/p\u003e\u003cp\u003eThe entire Manifold and Up-Pipe exhaust system are designed to maximize power and flow characteristics, lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy, and maintaining reliability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHigh-Flow Exhaust Manifolds\u003c\/strong\u003e\u003cbr\u003eCeramic coating is available as an option for High-Flow Exhaust Manifolds.\u003c\/p\u003e\u003cp\u003eCeramic coating was pioneered by the military and defense industries. Now considered a standard in high-performance applications like Formula 1 and military jet aircraft. This same process is available to you - today.\u003c\/p\u003e\u003cp\u003eThe Ceramic-Coating option enhances the existing benefits of the PPE Manifolds and Up-Pipes Kit which is specifically designed to maximize power and flow characteristics. Ceramic coating creates a thermal barrier and doesn’t absorb heat as quickly as raw metal.\u003c\/p\u003e\u003cp\u003eThis reduces the thermal cycle and surface temperature. The ceramic coating promotes even greater flow, which means lower exhaust gas temperatures (EGTs). Ceramic coating also offers long-lasting protection against moisture, road salts, oil, fuel, and other corrosive chemicals. Plus, ceramic coating keeps your PPE Manifolds looking great - for a long, long time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e304 Stainless Steel Up-Pipes Kit\u003c\/strong\u003e\u003cbr\u003eChoose the Ceramic Coating Option added to your PPE Manifolds and upgrade your GM 6.6L Duramax with the superior combination of PPE Manifolds with 304 Stainless Steel Up-Pipes Kit.\u003c\/p\u003e\u003cp\u003eComplete your upgrade with a PPE Stainless 3 Inch, 304 Steel Down Pipe.\u003c\/p\u003e\u003cp\u003eLML model requires modification on upper control arm bushing heat shield. \u003cbr\u003eUp-Pipe configuration may vary depending on your model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The factory downpipe (2001-2004 LB7 only) does not fit aftermarket manifolds and up-pipes.\u003c\/p\u003e","brand":"PPE Diesel","offers":[{"title":"Default Title","offer_id":54217199780115,"sku":"HFTD_116111000","price":1249.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/6472\/4499\/files\/116111000_6-HFTD.jpg?v=1779981517","url":"https:\/\/nolimitautomotive.ca\/products\/gm-6-6l-duramax-high-flow-exhaust-manifolds-and-up-pipes-kits-2001-2004","provider":"No Limit Automotive \u0026 Performance ","version":"1.0","type":"link"}
