250SX/ES Big Red Exhaust Differences?

[bbechtel16]

I was wondering if the the exhaust setup on the Big Red is identical to the SX because I was considering a Corbra Megaphone exhaust for the SX but after my friend got one I was like, too loud, (doesn't bother me but it bothers everyone else). Well I noticed That the Utility series is avalible for the ES which is quieter than the megaphone avalible for it (65 bucks more though :( . The part numbers on the Megaphone systems are slightly different between the SX and ES but I would guess it would take only slight modifcation to work. Any insight?

Nevermind, after some part number comparisons and some schematic lookups on bike bandit, I found out they aren't identical, close though, but I'm not gonna spend $166 for an exhaust I'll have to rig up.
