Okay here is the low down - Went to get car tuned, found out i had an exhaust leak - so no proper a/f ratios were coming out. I was told the manifold could be warped, so I have a couple of options - Buy a new manifold - if so, where would be a good place to find one? 2nd option - put two gaskets on instead of one (where would i get these, mazda dealer? or is there a shop that sells them?). What do you guys think? Thanks for any info/advise.

what kind of manifold is it? and can you just machine the manifold flanges flat again?

T04 flange, it was a cheap OBX manifold - i already new it was warped, and had it machined once, but it didn't fix the problem - I was warned of this.
