Here is our new K Series Sidewinder.

One of the design aspects we really wanted to have was keeping the turbo square to the engine and not having the inlet of the turbo facing towards the center line of the engine.

Also we wanted to have the best in class for boost control without going to a massive wastegate. The manifold will come machined to suit the 44/45/46mm waste range yet also allow the customer to cut the flange off and run a 50mm unit if desired. The internal sizing and flow will still out flow a 50mm unit.
We also believe this feature to be an industry first: a 4" down pipe with clearance for LHD brake master cylinders and their booster. It also allows wastegate plumb back and provision for a wideband to screw in.
On the manifold there is a mount near the turbo flange that allows the customer to make an extra brace to support the weight of the turbo system.

On the dump and manifold there are provisions to run a brace to keep the weight of the dump off the V-Band flange. The dump is machined for a 3.5" V-Band flange to make it easy for a full 3.5" exhaust or 3" system to be fabbed up. The manifold will also come with our innovative 50-55mm V-Band mounting system to allow turbos as small as a G25 through to a 6870 or down the track we will be releasing a weld on piece that will allow 70mm V-Band flanges to go on so you can run the big boi turbos like @garrettmotion G40 G42 and G45's or @precisionturbo 6870 all the way up to 8685's.

Well made, looks sharp.
Size: Large, Color: Blue, Size: Large, Color: Blue
I picked this up to have another nicer dress shirt. It's made of quality materials. I thought I should have it a little less big than I normally get so I sized down and that was a mistake. That's my fault though. Luckily it fits my wife so she's taking ownership. It fits true to size. The material feels good on your skin. It doesn't have that sheer look that a lot of of button up shirts do. It is is nice and thick. At twenty five dollars it's a good price.

fits well
Size: Large, Color: Blue
wanted a classic-looking western shirt to add to my wardrobe, and this embroidered button-down really caught my eye. The bright and bold white embroidery stands out beautifully against the dark blue fabric of the shirt. It gives off a very traditional cowboy vibe without feeling outdated or tacky. When I tried it on, I was glad to find that it fits comfortably across the shoulders and chest without feeling overly restrictive. The long sleeves are a great length, and the fabric feels durable enough for casual day-to-day wear. It works perfectly whether you want to tuck it in for a neater look or leave it untucked for something more relaxed. The buttons are secure, and the overall construction feels solid throughout. It is a striking shirt that strikes the right balance between style and everyday comfort.

Western Prop Top
Size: Small, Color: Blue
This is a nice western shirt, especially if you’re looking for something for a costume or themed event. It has that classic cowboy look with the embroidered details, which give it a bit of style without being too over the top. The fabric feels decent, it’s soft and comfortable while wearing it. It’s not premium-level, but it gets the job done for the price. The fit and design work well with jeans or boots, making it easy to pull together a full western outfit for a party, concert, or rodeo-type event. Overall, it’s a solid option if you want a good-looking western shirt without spending a lot, especially for occasional wear or costumes.

A very comfortable shirt at a good price!
Size: Large, Color: Blue
Comes out very soft once washed! I ordered this shirt when I saw it and was curious how stiff the material was. I was expecting something a bit more coarse since it was western wear, but was pleasantly surprised to find that once washed it became very soft. The shirt is also very light and airy, and allows the breeze through to cool you off. I was also impressed with the quality of the shirt. All the stitching is tight and neat, and there were no threads hanging loose to catch on anything. As far as sizing goes, it was exactly what they recommended based on measurements, and it fits great. The cut of the shirt is pretty nice also with a bit of a taper, and it looks really good on (according to my wife, anyway). The shirt is versatile enough to wear out to dinner at the steakhouse, or to work in the yard. Bottom line: The shirt is comfortable, fits well, is good for work or going out, and a great deal for the money!

Looked amazing… but not built for broader shoulders
Size: Small, Color: Blue, Size: Small, Color: Blue
I got this for my husband because he’s fully leaning into his cowboy era lately (new boots, new attitude, the whole thing), and I thought this shirt would seal the deal. First impression—honestly impressed. The color is really nice and the embroidery detail looks great in person. It doesn’t feel cheap at all and definitely looks more high-end than expected. For reference, he’s about 5’6”, 140 lbs with an athletic build. The shirt almost worked—it fit well through the body and could be fully buttoned, but the shoulders were just too tight. As soon as he moved his arms, it felt restrictive, like the seams were being pushed to their limit. Which is a shame… because wow, he looked GOOD in this. And that’s coming from someone who doesn’t usually love this style. I’d say this shirt runs better for slimmer or narrower builds. If you’ve got broader shoulders or any upper body muscle, you may want to size up or skip this one. Overall, great quality and style, just not the right fit for an athletic frame.
