No. Expect to if you ever go with long-tube headers.

I needed one on my 95. I don't know if the locations are different from a 93 but I was about 2 inches short on the passenger side.

I have 95 style mac's on my 96 and I didn't need them. I did have to pull the passenger side wires out of the large convoulted (sp?) tube a little to allow me to run the wires like I did.

My AS&M headers didn't need them.

Also, my MAC headers on my 94 didn't need them either.
