Description

This aFe POWER turbo downpipe is engineered to outflow and outperform the restrictive, factory downpipe on the 2011 – 2015 GM Truck with V8-6.6L (td) engine. The mandrel bent, stainless steel tubing offers smoother transition bends for increased airflow, delivering quicker turbo spool times. CNC machined V-band inlets and outlets ensure a factory style, 360-degree sealing surface. Both inside and outside surfaces of the downpipe are ceramic coated to reduce EGT’s even in the most extreme environments.3 IN Mandrel Bent Stainless Steel Tubing409 Stainless Steel100% TIG-WeldedCNC Machined FlangesMACH Force-Xp 3 IN 409 Stainless Steel Downpipe GM Diesel Trucks 11-15 V8-6.6L (td) LML
