The exhaust is the HKS Hi-Power exhaust which goes from the primary cat back, and eleminates the secondary cat. Yeah my 91 came with 14 in. wheels, but even with those it ran the same times. I think in 91 and 92 few mr2's came with limited slip, and then, in 93, it became standard. Also, I know it has limited slip because that's what the burn out marks on my garage floor tell me.
