I didn't realize it till i got home that i forgot to mention it was a 22R, so would the supra option till work since i saw your picture showing that it had EFI. The other thing is reason why i said 2.25" from the Y off the manifold to the muffler is this is what i've seen done and i've even asked a few shops. I can do a 2" if that would be a better ratio for both 2" in and out. Just what someone suggested so was going to give it a try.
