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).

Decent Suit, But the Sizing Is Way Off
Color: Black, Size: XX-Large
I really wanted to like this suit because the material and overall look are actually pretty decent for the price. The jacket and vest fit about how I expected for an XXL—no complaints there. But the pants? I swear they could fit a small horse. I ordered the WULFUL Men’s 3-Piece Slim Fit Suit in Black, XX‑Large, and the pants that came with it were massive. They’re supposed to be part of a “slim fit” set, but the waist and leg width are so oversized that I have no idea what size they were aiming for. It honestly feels like they just toss in whatever pants are nearby. If you’re buying this suit, be prepared for a trip to the tailor… or to exchange the whole thing. The suit itself is okay, but the sizing consistency is terrible.

Good quality suit, but size up.
The suit seemed was very good quality. It was too small, so size up. We had to send it back, but the refund process was very simple and easy! Thank you for the easy transaction!
