Only 10 screws included

I don't know if it's a Revain problem or something but I'm missing 2 screws. It really bites because I was planning to do it tonight and now I can't. I'm sure the screws are great but it's good to have them all.

Pros
  • Durable finish
Cons
  • Some small things

Very good quality item here

Very good quality item here. I've tried so many brackets on my manifolds and turbo manifolds and finally found the ones I will be using from now on. The concept is so simple and yet it works so well. I don't have the patience to deal with what you attach with steel wire and slip around your hands. Highly recommended to invest in them, you won't regret it. A little extra coin but well worth it.

Pros
  • Very fast delivery
Cons
  • Slightly wrinkled

No leaky headers! good for performance parts and accessories

Rating could have been 5 stars but was missing 1 "E" clip and 5 extra drip holders. It would also be nice if they included at least some instructions. On my LS1, the first bolt pass is 11 ft.lb, the second/last pass is 18 ft.lb. The kit includes 4 clamps, the ends of which are bent over and placed on the second and fourth screw from the front. Probably common sense, but a small piece of paper with the slightest direction would help!

Pros
  • Stylish and modern design
Cons
  • Trade-in available
