ARTEC Performance is an Australian manufacturer of high-quality exhaust manifolds that has revolutionized the industry with its pioneering SUS347 stainless steel precision casting technology. All manifolds are designed using CFD simulation and tested under real-world conditions.

Atlas / Vortec 4200 T4 with divided single 50mm wastegate!

Not one person asked for this BUT I think this engine has not received the attention it deserves.

We have been working with @nivlac57 and @motionautotv. The 4200 Straight 6 from @generalmotors was released in a Blazer, but the ability for this engine to hold itself together at now over 700whp through an auto has been documented by Calvin over at the Nivlac57 YouTube Channel. We have designed this and tested on a number of chassis to allow easy fitment in LHD builds.

This has been designed to accept up to the larger frame @garrettmotion G45’s,  @precisionturbo 75's and 85's as well as @borgwarnerboosted S400's. Again we have machined the manifold to suit a @turbosmarthq 50mm wastegate, but can run a 60 if you cut the flange off (as the runner is designed to flow the 60).

If you’re on the fence read this
Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash, Special Size: Low Stretch, Size: 40W x 30L, Color: Iced Light Wash
In all honesty, I was skeptical about ordering jeans from Amazon. I’ve always bought my jeans in stores, but I figured I’d give it a shot. I ordered these jeans for an upcoming outdoor wedding because I wanted something lighter and thinner. They showed up today, and I threw them on. They fit great, feel good and comfortable, and they don’t look cheap. I’ll mainly be using these for outings, so I can’t really attest to the durability as far as working in them, but I’d still suggest them. For reference, I’m 5’8” and 230 lbs with a husky build—kind of fit, kind of fat.

A Great Buy - But Might Be Too Long
Special Size: Low Stretch, Size: 34W x 32L, Color: Dark Midnight Wash
These jeans are an excellent buy! I have only bought Eddie Bauer jeans for the last 25 years, but this time I couldn't find my size in the correct style. I prefer classic/relaxed in dark blue. I don't like the "pre-washed" or worn look. The Dark Midnight Wash was exactly what I wanted - new jeans. The waist measurement was perfect. Unfortunately, the 32 length was waaay too long. (All the Eddie Bauers were 34x32). So I just did an exchange for a 34x30, which should be good. Eventhough the length was too long, I'm still giving 5 stars. Different manufacturers cut sizes differently. It is what it is. And the return process was EZ and the replacement size was in stock. Seriously, there is really no quality difference between these Amazon Essential jeans and my old $60 E.B.s No one sees the label anyway!

Weird sizing, snug in some places and much more “relaxed” in others
Special Size: Rigid, Size: 33W x 28L, Color: Black
Comfortable and close fit around waist, buttocks, crotch - but from thigh down trouser cuff it’s a VERY relaxed fit, much bigger than I need even with thick muscular legs. Not quite clown pants or bell bottoms, but a still a strange look. I’ll probably be sending them back.
