*IMPORTANT!*
I am making these manifolds in an effort to further assist people who do not have the means (or
experience) to make these themselves. I have been racing and fabricating long enough to have found
what works, and what does not. This is the design, material, and quality I will be using on my personal
car when I push for the 8's.
I am not going to compare or attempt to compete with any other person or business. So, PLEASE! Do
not call or email me asking what I think of "so and so's" manifold.
"IF" I provide any sort of additional discount, it will be at my discretion. I would be willing to give a
discounted price on multiple item orders. If you have a multiple item order you would like to place,
please email me and we can discuss the details.
