i got a question about my exhaust. one time i had the exhaust all off due to binding when the pipes got damaged and the sound was mean coming from the 351w (1992 flareside) and i love it up i got to admit. okay is it bad for the truck to be running with open manifolds? or any way bad because i got to take them off for more fixing up work and the truck will do travel MAYBE by trailer idk yet depending on the outcome....????
