also i wanted to know what companys make smoke stacks for this truck i cant seem to find any

 

Stacks are universal, find some that you like and run with em.

As for things to watch for, SCAs!

 

SCAs?

 

SCA's are in your coolant. You have to monitor them or the high levels will eat away at the insides of the engine. You should read this...
