no worries on the hijack it happens.
the GXP exhaust is 2.5 O.D. from the cat back to the Y then 2.25 O.D. past the Y to the mufflers. then 2.5 out to the tips.
the SSEi exhaust i took off is 2.25 from the resonator back to the Y then 2.0 to the mufflers and 2.25 to the tips
you'll have to ask Danthurs on the 99 down as i don't think the two will swap out
