Features of 2004.5-2010 Duramax Downpipe

This downpipe offers a 20% improvement in exhaust flow over the factory pipe, providing you with a notable performance boost. Its stainless steel construction ensures durability, even under extreme conditions. The included heat-wrap helps retain heat within the exhaust system, reducing engine bay temperatures and keeping performance optimized. Additionally, the downpipe does not interfere with your emissions system, meaning you can enjoy the benefits without worrying about compliance.

Performance Improvement

By upgrading to this 3" inch turbo downpipe you will immediately notice an increase in exhaust flow out of the turbo. This smoother airflow helps reduce exhaust gas temperatures (EGTs), which allows your engine to operate more efficiently, especially during heavy towing or competitive use. The enhanced flow improves your vehicle's performance, giving it an edge in power output.

Great Toy, but Big Dogs Destroy the Squeakers Fast
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Large
My big dogs had the squeaker torn out in no time, but my little dog absolutely loves this toy. It’s the perfect size for her, and she carries it everywhere. Durable enough for small pups, just not tough enough for heavy chewers. Still a fun toy overall!

Fun for dogs
Color: Green/Alligator, Size: Small
Smaller than I expected, but the two little dogs love it! They love shaking it, making it squeak, tugging it against each other & chasing it when I throw it to fetch. They often sleep laying on it.

WEIRD feature - requires a water bottle
Color: Cow, Size: Large
Cute, but buyer beware. Maybe the description said this, but who would think to read for this.... You have to insert an empty bottle (like an old water bottle) for it to make the crinkle noise. There is a velcro spot at the base where you can open it and insert the water bottle for the noise factor and your dogs entertainment. I've yet to do that, but feel like my dog is gonna figure out the velcro and get the bottle out in no time. Seems like a waste of money. I could just give her an empty water bottle without the toy for free.

Best dog toy!
Color: Multicolor/Alligator & Wild Duck, Size: Medium, Color: Multicolor/Alligator & Wild Duck, Size: Medium
Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.
