Product details

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. 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. ATLAS 3 IN Steel Downpipe GM Diesel Trucks 04-10 V8-6.6L (td) LLY/LBZ/LMM ATLAS 3 IN Steel Downpipe

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is quoted in your reviewed estimate before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
