GMC Turbocharger Down Pipes

If you are looking for a highly engineered down pipe look no further than the aFe Power Mach Force XP Down Pipe. Down pipe is 100 percent TIG welded and uses a stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased intake charge and more power. Race proven strength and durability. Designed using a resonance chamber to help reduce the in-cab resonance found with other down pipes. All hardware and brackets are included for a hassle-free installation.

“Optimize your 01-04 LB7 GM diesel’s airflow to improve throttle response with aFe’s ATLAS 3″” turbo down-pipe. Constructed from 3″” mandrel bent steel tubing for maximum flow, the larger tube diameter and smooth transition bends allow increased airflow between your OE turbo and exhaust to reduce EGT’s for quicker turbo spool times. The CNC machined heavy duty inlet flange with turbine gasket and V-band outlet flange ensure an OE-style, 360 degree sealing surface. Coated with a black finish, the ATLAS turbo down-pipe is wrapped with thermal header tape to reduce EGT’s for improved performance and durability. Flow and Performance: The ATLAS turbo down-pipe is made from 3″” mandrel bent steel tubing offering smoother transition bends for low turbulence to deliver quicker throttle response. Perfect Fit: The ATLAS turbo down-pipe is an upgrade to the OE down-pipe and utilizes the factory mounting locations for true bolt-on performance. Finish: This down pipe is coated with a black finish and wrapped in thermal header tape for better insulation. This reduces EGT’s and under hood temperatures. Note: This system is not currently CARB exempt or available for sale in California, and cannot be used on any vehicle registered with the California Department of Motor Vehicle. This item in not legal in NY for use on vehicles with CA emissions.”

ARMOR LITE Series exhaust systems are a value option with the same fitment, performance and sound as the premium products from MBRP. Heavy-gauge Aluminized Steel tubing helps to resist dings and dents caused by debris under your vehicle. This material can be a great choice for you if you live in a dry climate that does not see much precipitation, or if you are looking for great sound on a budget. All of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine cylinders, allowing it to produce more power and improve vehicle performance and longevity.

“The aFe ATLAS turbo down-pipe is engineered to outflow and outperform the restrictive, OE down-pipe on your 2004.5-2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with the Duramax V8 6.6L turbo diesel. The 3″” mandrel bent steel tubing offers smoother transition bends for increased airflow, delivering quicker turbo spool times. CNC machined V-band inlets and outlets ensure an OE-style, 360 degree sealing surface. Coated with a black finish, the ATLAS turbo down-pipe is wrapped with thermal header tape to reduce EGT’s even in the most extreme environments. Flow and Performance: The ATLAS turbo down-pipe is made from 3″” mandrel bent steel tubing offering smoother transition bends for low turbulence to deliver quicker turbo spool times. Perfect Fit: The ATLAS turbo down-pipe is an upgrade to the OE down-pipe and utilizes the factory mounting locations for true bolt-on performance. Leak-Free Seal: High quality OE style CNC machined V-band flanges are used for a complete 360 degree sealing surface. Finish: This down pipe is coated with a black finish and wrapped in thermal header tape for better insulation. This reduces EGT’s and under hood temperatures.
