looks good
every thing fit without any modifications. just need to be careful to place the right pipes in the right spot. Does not come with gaskets, need to buy them.

Need better quality control
Poorly made: one is poorly machined see the picture of it; also there is no O-ring at the bottom of the vent tube: see pictures of the aluminum ones. I believe these black one will leak. I will send them back. Also no instructions.

Tight fit. I needed to trim my manifold
UPDATE: I am a dummy. I was testing without the gasket. The gasket fills the gap and now it work; I still needed to trim or else it wouldn’t fit. Hopefully it doesn’t leak but for now it’s working out. Works with my TBSS and LM7 intake, should clear LS1 intake and will easily clear a hi ram.

Impressed!!!!
Beyond impressed and couldn't wait to write this review. Fits perfect! Install loose and tighten at the end. 2002 silverado with a LS1. Let me reiterate, it fits perfect! If you have to bend anything, you have installed it wrong. Stays low to the valley plate and fits under the truck intake by a mile. HIGHLY recommend, can't beat this price. This is an important piece along with a catch can on any LS build. Cheap insurance!

Missing pieces needed to install
Doesn’t come with the mini gaskets/seals to the block. Makes sense why everyone says it leaks.

Fit loose then tighten. fits great
So far seems to be perfect. I did flip the center section so it's just black. But assemble loose and tighten everything up on the motor and fit perfect. I'm building another ls and will get another one.

No Good
This thing is junk. Yes, it looks good. But it leaks at all of the flare end connections. I had to pull my intake manifold and replace this kit, antifreeze leaked at 9 connections. Didn’t matter how tight the connections were. Don’t waste your time. My truck: a 2006 Silverado 3500 4WD LQ4 6.0.
