In one of the old versions (V1? Hell if I know, I don't know how to check) the Rocket MK1 had deadly exhaust, far more powerful than what's in the newest version.
To the point that you could just float past the opposition and they would explode.
It saddens me that this isn't possible in the newest version.

Is there a mod that can input the old version of the rocket?
Or can I manually change the power of the exhaust in the newest version?

Yeah, I think the files are in Base.rte/Actors/Rockets or something similar. Changing the lifetime of the particles should be enough.

Same here.
I think its one of the stupider things in current CC, it was perfect before, and now it's ruined.
Seriously, its freakin' rocket fuel burning at hundreds of degrees... And its harmless... Mofukka.

It can be recreated with great ease, but honestly, who can be bothered doing it?

The fact of the matter is that leaking combustibles from a rocket device would not seep the way they do in game, they would just ignite. Be glad Data didn't do it that way.

it would be better if the fire set actors alight, and knocked them away roughly.

Caustic, acidic, hot, lethal gasses = dead passengers.

i agree with crazy mlc but whatever its the future does it really matter how the current rocket works? however if something like a ronin rocket or a coalition rocket is made it could have deadly exhaust.
