Banks massive 3.5" boost tubes are the largest on the market, flowing 26-45% more air than stock! Smooth mandrel-bent tubes deliver more air to your engine while reducing boost pressure loss resulting in quicker turbo spool and more power. Banks Boost Tubes are the largest charge air cooler pipes in the industry, measuring in at a full 3.5 inches. Every other competitive product on the market tops out at just 3.0 inches, and your factory pipes are only 2.5 inches with crushed bent corners and flimsy plastic components. By contrast, Banks Boost Tubes are made of high-quality aluminized steel for maximum strength and durability. With Banks Boost Tubes' smooth bends, your turbo can spool quicker thanks to improved boost pressure retention for maximum horsepower. The Boost Tubes work with the stock Duramax intake components by using proprietary high-strength 5-ply silicone hoses. Unique to the 2020+ model, a pair of billet aluminum cold-side adapters are also used for the intercooler connection and the throttle body. These are specially made for the airflow requirements of the L5P and feature a Venturi-like taper on their inside diameter to maintain boost pressure and volumetric flow.Key Features: Huge increase in size and flow over stock and competitors (3.5" vs 2.5").Hot Side flows 490 CFM @ 12" vs stock 388 CFM. Cold Side flows 635 CFM @ 12" vs stock 435 CFM. Constant 3.5in diameter tubing for the best flow. Billet venturi couplers maintain boost pressure. Mandrel-bent aluminized steel construction.

Nice kids suit
Size: 5, Color: Light Blue
This is a nice way to play up your son's sophistication. It is a linen suit, but isn't a true linen. It is a blend of linen, polyester and spandex, which isn't a bad thing for kids since it has a softer feel. Sizing was accurate. I'm looking forward to when he can wear this to a formal occasion.

A suit I ABSOLUTELY love ☺️
Size: 14, Color: Lilac
This 3 piece suit is one of our FAVORITES! I firstly love the color which isn’t one I had seen very often and it’s not to bright, rather more neutral and formal. The suit is of luxury grade and standard with the matching durability along with perfect stitching from buttons to seams. The suit came with 3 flawless pieces (blazer, slacks, and vest) all of which are true to size, well fitting, low maintenance, and very comfortable. I couldn’t think of a better special occasion suit or gift, and I HIGHLY recommend ⭐️⭐️⭐️⭐️

Such a nice suit!
Size: 14, Color: Beige
I was pleased upon getting this suit for my son. I really like the color, which is kind of like an oatmeal color. Nice and light color. The material is light and thinner, but very comfortable. It fit my son really well. It’s not lined or the best quality suit, but because it is a linen suit, it works out and look really good. I would recommend this one, especially for more of the summer/spring time.

Great vest
Size: 12, Color: Black
Great vest. I love the slim fit. It looks very nice on my son, not baggy or boxy looking like some vest. My son has used it for several occasions including a wake, a Beta Club induction, awards day, and soon his graduation celebration at church. The quality and material are good. Definitely worth what I paid.

Elegant Color and Very Well Made Vest
Size: 14, Color: Light Grey, Size: 14, Color: Light Grey
The vest is really nice and great quality, but it does run a little smaller than expected. I would suggest sizing up if you want a more comfortable fit. Other than that, it looks very sharp and well made.
