Hooker's new cast iron small-block Chevy exhaust manifolds offer an increase in performance and visual appearance over stock-style manifolds. Their compact design fit into a wide variety of replacement and engine swap applications. This means you get the traditional look and easy fitment of a stock style exhaust manifold but now with a smoother, cleaner appearance, plus more modern features. These manifolds are cast out of high silicon-molybdenum ductile iron for high temperature strength and better resistance to oxidation and cracking. Internally these manifolds have a larger than stock 1 5/8-inch cross-sectional area and 2 1/2-inch outlets for better air flow and improved performance. Designed for rectangular port heads, these manifolds fit many popular GM applications including standard straight and Vortec straight plug head designs. Finishes include natural, silver, black, and titanium ceramic. Gaskets and hardware are included, along with weld-on flanges to aid in downpipe installation.
Features:
- A smoother, cleaner appearance compared to original exhaust manifolds, while maintaining a factory style look and feel
- Made from high silicon-molybdenum ductile iron for high temperature strength plus resistance to oxidation and cracking
- Designed with a larger 1 5/8? cross-sectional area and 2 ½? outlets for better air flow and increased performance

Great low cost USB C to 4K HDMI splitter adaptor
Color: Black
The Anker USB C Hub 5-in-1 USBC to HDMI splitter with 4K display with one powered USB c and 2 USB A ports works flawlessly and is a perfect travel companion or simple and inexpensive desktop dock to connect a moderan USB C only laptop to a large monitor up to 4K resolution. It supports 4K at 60 Hz so not for high speed gaming but it is flicker free for daily work where running at 60 Hz provides a clean looking 4K display. The USB C and USB A ports work perfectly. I already have four of these in different port configuration but wanted the 4K extension for travel and this was the best one for quality and bang for the buck.

Compact hub that punches well above its size
Color: Black
This hub handles 4K HDMI output and three data ports cleanly without any noticeable lag or connection issues. The powered ports on both the USB-C and USB-A sides are a useful feature for running peripherals without draining the host device. Compact enough to leave plugged in permanently without getting in the way. Works reliably on MacBook and Dell machines as described. Good value for a well-built hub with a solid feature set.

Compact, Travel friendly, Works well with ROG ALLY
Color: White
This is a compact and well built adapter, and it is travel friendly. I use it for my ROG ALLY when I don’t want it docked and still need charging and other device inputs. It has just about enough ports for what I need, usb-c power delivery port for charging (ROG ALLY can still run at maximum performance using this with a 100W charging brick and a cable that allows 100W power pass through). I use the remaining USB-C port and two USB-A ports for external hard drives or gaming controller 2.4Ghz receiver. Transferring files between ROG ALLY and an external SSD with this adapter is fast, could reach above 380 mb/s. All the device inputs were as advertised, “plug and play”. The hdmi port also gives me an option to connect my ROG ALLY to TV when I don’t have the dock which takes up more space for traveling. One thing to note, you will have to use the USB-C port on your PC which provides more power (usually at the back and not on the front of the pc), if not plugged in to a power source. When I received my first order, I plugged it into the front USB-C port of my mini PC, just for my wired keyboard and mouse, the computer didn’t recognize it and couldn’t get any input from my keyboard and mouse. I returned the first one and thought it wouldn’t work as I expected. A few days later when I was using another Anker 7 in 1 USB-C adapter, I ran into the same issue but I know that adapter had been working well, then I realized I had to plug it into the port on the back of the PC. So I got this again and tried, it just worked like a charm. Hope they actually mentioned it on their product page so I wouldn’t have to return the first one. The cable length on this adapter is just right, not too long or too short when using with ROG ALLY (not hanging, since the cable is pretty sturdy, when I picked up the ROG ALLY, the adapter just comes along).

Reliable Hub That Gets the Job Done
Color: Blue, Color: Blue
Solid Anker USB C hub that does what it’s supposed to do. Ports work well and it’s easy to use right out of the box. Only downside is the hard plastic casing, it feels fine, but I could see it cracking if something heavy drops on it.

Helped transfer data from Samsung Galaxy S21 with broken screen.
Color: Black
Helped me transfer data from a Samsung Galaxy S21 with broken screen. Simple put USB C end into phone , grab HDMI cable and plug into hub , then plug HDMI end into a monitor. Then grab a wireless keyboard & mouse and plug dongle into hub. Your phone will output to monitor and you can transfer data via Smart Switch using keyboard & mouse. Will only work if phone is unlocked I found on S21.
