This MACH Force-Xp 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.

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.

Fitment Note:
This Turbo Down-Pipe will only fit 2015 models manufactured before July 2014 equipped with a non-flanged down pipe.

Emissions Disclaimer:
This Turbo Down-Pipe is 50-state legal, please see CARB EO# D-550-45 for details.

All aFe exhaust systems are engineered and manufactured in our Corona, California facility.
