Alright, what's up?

I was wondering if there was a way to distinguish the original 40s from the delta 40s just by looking at the mufflers. Are the numbers on the outside different? My friend just bought a 92 LX with some 40's but I am now trying to figure out if they come with the delta technology or not.
