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

Love this it works so well
Size: 10FT, Color: Purple
The link is good. The color is beautiful, they're very easy to use. The charging speed is amazing. They help keep my battery charged all day long, very versatile. It weighs absolutely nothing. And you wanna talk about durability?My dog chewed it and they're still working.

Decent
Size: 10FT, Color: White
Would of gave a 5 star rating but in terms of quality it’s decent as far as advertisement of it being 10ft is a lie I still had one of my original apple 10ft cable and these are technically 8-8.5ft. So far both boxes and cables still functional and working 5 months later better than most chargers you will buy at a gas station, that will only last about 2-3 months.

Favorite charger
Size: 10FT, Color: Yellow
This is my 3rd purchase of this brand of charger (different colors). The yellow color is just as pictured. These chargers always fit flawlessly with my iphone15 pro. The charger provides a fast and lasting charge for my phone, iPad, or anything else I connect it to. I love the bright color options. I highly recommend this charger because they are durable and provide a quick, long lasting charge.

Perfect charger
Size: 10FT, Color: White
Very impressed with how quickly the charger works. The longer cable has made it easier to use the phone while charging and sitting on the couch. No issues with the cable getting tangled or fraying like I have had with others, or pinching and breaking the connection.

Life changing little screen
Size: 15.6" 1080P, Size: 15.6" 1080P
I was losing my mind trying to work from home off a single laptop screen. Secondary displays were not connecting to my computer outside of the office, IT could not figure out the issue so I was doomed to single screen anytime I worked from home. A co-worker suggested I take a look at this style of screen. I had my doubts that it would work with my lap top, and lo and behold I am back in action with a dual display. It comes with an HDMI cord option and a USB-C cord option (you do not need to buy separate cords, they are included). I used the USB-C as it also acts as a power cord to power the display. It took two seconds to hook up, and with one setting change on my lap top the display successfully extended (does not just duplicate your display, it will allow display extension as well). The image quality is more than sufficient for work (no opinion on PC gaming) and settings such as brightness were easy to adjust. It's the perfect size for use with my lap top screen, and they had plenty of additional size options. The built in stand allows two screen angles, and acts as a cover when not in use. For the price this thing is absolutely clutch, don't waste money on expensive displays - you can use this with any USB-C capable device so it can travel with you for work or fun. I will be interested to see if it has longevity, but for now I'd give this thing 10 stars if I could.
