Nitrous Express GM EFI Race Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Warranty Certificate of Origin

Okay shirts if they fit. Neck stretches out some with washing.
Decent shirts. It's difficult to buy clothes online because you don't know how they'll fit until they arrive. The small was too small, and the medium is just a little loose. I'm 5'8" and 150 pounds after losing 65 pounds in a year. I work out and have some muscle. Shirts look good on my chest, but the sleeves are a little too long, and the neck is starting to go bacon after just two washings.

Not worth the price.
Color: 2 Pack(black+white), Size: XX-Large
At best these T-Shirt should be in a 4 pack at maybe $10. Quality is not good, they are very thin, very stretchy and the collar does not hold its shape. Would not buy again.
