aFe Power 409 Stainless Turbo Down-Pipe | 2011-2015 Chevy/GMC Duramax LML 6.6L

This aFe Power turbo down-pipe is engineered to outflow and outperform the restrictive, factory down-pipe on the 2011-2015 Chevy/GMC Duramax LML 6.6L. 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.

Flow and Performance
This turbo down-pipe is made from 3" mandrel bent stainless steel tubing, offering smoother transition bends for low turbulence, and delivering quicker turbo spool times.

Ceramic Coating
This down-pipe is ceramic coated inside and out. This coating developed by the aerospace industry is used to lower under hood temperatures by insulating the stainless steel tubing. The satin aluminum finish is chip and heat resistant up 1600 degrees.

Leak-Free Seal
High quality factory style CNC machined V-band flanges are used for a complete 360 degree sealing surface.

Retains Factory Sensors
This system was designed to retain all your factory sensors for a hassle-free installation.

Perfect Fit
This turbo down-pipe utilizes high-quality OE style flanges and factory mounting locations to provide stability and a direct fit.
