Banks Boost Tube Upgrade Kit 17-19 GM 6.6L Duramax L5PThere's definitely something to be said of how cool it looks when you pop the hood of your Duramax and see a massive 3. 5" diamater red pipe dropping through the center of your engine bay. But, when you fire it up and the first thing you notice upon take off is how much faster your turbo spools, you'll know that the upgrade was all worth it.

There's definitely something to be said of how cool it looks when you pop the hood of your Duramax and see a massive 3.5" diamater red pipe dropping through the center of your engine bay. But, when you fire it up and the first thing you notice upon take off is how much faster your turbo spools, you'll know that the upgrade was all worth it.Banks Boost Tubes are the largest tube in the industry at a full mandrel bent 3.5" compared to competitors’ 3” and the stock 2.5" crush-bent tubes. Made of high-quality aluminized steel, Banks Boost Tubes allow for a quicker turbo spool by improving boost pressure retention (increasing air density) between turbo, intercooler, and intake resulting in maximum horsepower.
The Banks Tube Upgrade Kit works with the stock Duramax intake elbow and intercooler by using proprietary high-strength 5-ply silicone couplers and a unique billet aluminum cold-side adapter to further boost airflow.

Perfect Personal Item , travel Size Bagpack!
Color: Black, Color: Black
I’m so happy with this travel backpack!! Roomy and you can pack a pair of shoes also underneath. I recently went on a Cruise and had to fly into Florida coming from California, two different climates. I easily pulled off my sweats and shoes and slipped into a pair shorts and swimsuit and flip flops at the airport , because I had it all and 2 of my 3-1-1 bags etc. Another great feature is the see thru zip compartments ! Endless pockets and this bag is consider that “Personal Item” that stows under the seat in front of you. Quality is great and it’s a beautiful bag! Price , amazing Value!

Nice personal item for travel
Color: Black
I recently used this bag on my cruise. It fits perfectly under the seat for a personal item. The quality is nice and the bag is spacious to back many items. The only thing I didn’t like is that I kept having to adjust the straps due to them coming loose.

Hidden Gem!
Color: Desert
Huge and suitcase like on the inside. The zipper is the same color as the backpack and looks luxurious. Very soft and cushy even with heavy stuff in it. Like a laptop. Which there is a specific place for it that is cushioned. But my favorite by far is the clear pockets on the inside. I like that you can see what your getting out of your bag and where to find what. Also the outside pockets are really useful! And kinda incognito which is great for if you want to put valuables there. You can use this for travel, school and work. It's very versatile. Very good for organization. Comgortable and easygoing. Quality is 5/5.
