Description:
Upgrade the restrictive factory turbo downpipe/exhaust front pipe on your 6.6L Duramax Diesel V8 (2004.5-2010 Chevrolet Silverado / GMC Sierra 2500 / 3500 HD) with this high-flow, heat-wrapped, full 3" stainless steel downpipe. Designed to replace the crushed factory turbo downpipe, this upgrade ensures better exhaust flow, reducing backpressure and improving turbo spool-up. The enhanced airflow contributes to significant gains in horsepower and torque, as well as lower exhaust gas temperatures (EGTs), which are crucial for maintaining engine health and performance.
The stainless steel construction ensures durability and resistance to corrosion, while the heat wrap helps manage under-hood temperatures by preventing heat from radiating into the engine bay. This downpipe is compatible with OEM or factory-style drop-in turbochargers and requires no tuning, making the installation process straightforward and hassle-free.
Compatibility:
- Chevrolet Silverado 2500/3500 HD: 2004.5-2010
- GMC Sierra 2500/3500 HD: 2004.5-2010
Replaces the following GM Part Numbers:
- 98050150
Additional Benefits:
- Improved Performance: By optimizing exhaust flow, this downpipe reduces backpressure, enhancing turbo spool-up and delivering more power to your vehicle.
- Durability and Reliability: The stainless steel material provides long-lasting performance and resistance to harsh conditions, while the heat wrap protects surrounding components by reducing under-hood temperatures.
- Easy Installation: No tuning is required, making this a simple bolt-on upgrade that can be completed with basic hand tools.

There is no side to side stability
Size: 28 Inch
This product was easy to assemble and install and came with all parts. The product itself is very sturdy, looks good with a nice industrial aesthetic BUT - there is ZERO stability side to side (lengthwise) as the plates which attach to the wood are too small. I have them set closer than the picture so it is not an issue of being too far apart. If anyone else had this problem AND FIGURED OUT A FIX FOR IT - please share!!

Fairly stable. Good value for the price
Size: 16 Inch, Size: 16 Inch
Great set of stands. You have to tighten them pretty snugly to minimize wobble. Given they are metal they’ll have a little bit more give than solid wood. Even so,
a tall desk I built with them remains stable and level.

I love it!!!
Size: M Desk Unfinished 3/4-in and 1/2-in
Easy to assemble, all the pieces were in the box. I set everything out to be sure. Instructions were easy and clear, took about 10 min to put together.
Seems to be quality pipe, strong stable build even at just hand tight. When I put the desk top on it was already level so bonus there.
This kit is a great value, before I found the M desk I was looking on Pinterest for pipe leg designs thinking a trip to the hardware store and I could make it for cheaper, which was not the case. I 100% will recommend, and will purchase again.
