aFe MACH Force-Xp 3in 409 Stainless Steel Down-Pipe 11-15 GM Diesel Trucks LML V8 6.6L (td)

This aFe POWER turbo down-pipe is engineered to outflow and outperform the restrictive, factory down-pipe 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 down-pipe are ceramic coated to reduce EGT's even in the most extreme environments.This Part Fits: Year Make Model Submodel 2015 Chevrolet Silverado 2500 HD High Country 2011-2015 Chevrolet Silverado 2500 HD LT 2011-2015 Chevrolet Silverado 2500 HD LTZ 2011-2015 Chevrolet Silverado 2500 HD WT 2015 Chevrolet Silverado 3500 HD High Country 2011-2015 Chevrolet Silverado 3500 HD LT 2011-2015 Chevrolet Silverado 3500 HD LTZ 2011-2015 Chevrolet Silverado 3500 HD WT 2015 GMC Sierra 2500 HD Base 2011-2015 GMC Sierra 2500 HD Denali 2011-2015 GMC Sierra 2500 HD SLE 2011-2015 GMC Sierra 2500 HD SLT 2011-2014 GMC Sierra 2500 HD WT 2015 GMC Sierra 3500 HD Base 2011-2015 GMC Sierra 3500 HD Denali 2011-2015 GMC Sierra 3500 HD SLE 2011-2015 GMC Sierra 3500 HD SLT 2011-2014 GMC Sierra 3500 HD WT
