Passenger Side Up-Pipe | Gm/Chevy 6.6L Duramax 2001-2016

The Passenger Side Up-Pipe for the GM/Chevy 6.6L Duramax 2001-2016 feeds exhaust flow from the passenger-side exhaust manifold to the turbocharger, and this stainless steel replacement delivers higher flow and lower turbulence airflow for increased power. It's our best selling Duramax passenger side up-pipe.

The factory up-pipes live in a brutal thermal environment, cycling between cold starts and high exhaust temperatures. When the passenger side up-pipe leaks or restricts, you lose performance, throttle response softens, and turbo efficiency drops. This direct replacement fixes that with higher flow and lower turbulence, which delivers exhaust pressure more efficiently to the turbo, something you'll notice most on tuned and deleted trucks.

It's built from high quality stainless steel for lifelong protection, designed to outlast the factory OEM pipe, and shipping is included in the price. In the box you get the stainless up-pipe as a direct replacement, the required hardware, and an installation guide. A couple of fitment notes matter here: this is a non-EGR up-pipe, so the EGR system must be removed on LB7 and LLY through LML engines, and 2015-plus trucks may need a modification to the shock mount.

It's compatible across the 2001 through 2016 model years on the Chevy and GM 6.6L Duramax. If you have questions about fitment or EGR removal compatibility, call (888) 830-2588 or email sales@thedieseldudes.com. Standard shipping takes 4-8 business days, with possible added freight to Alaska, Hawaii, and some Canadian locations. This product is eligible for return within the first 30 days if it hasn't been used.
