Finally got my grand rock stacks in today and am putting them on tomorrow hopefully. But a guy at work said that having stacks will screw up my trans if I didn't have a built one. Is this true I don't really see why it would be any different than what I am currently running with the 4 inch into duals. Is this guy just blowing smoke. I think I have a built trans anyways just don't want to fry it. Sorry for the dumb question
The only dumb question is an unasked one. That said, this will absolutely cause no tranny issues except from the fun you will be having with the new exhaust. He is the dumb a**.
tell that guy he is a idiot!! haha thats the stupidest thing i've ever heard. he must think stacks give the truck 400 more foot pounds of torque or something
