So one person (with only 3 posts) tells you what you want to hear and you believe him?? I think everyone on hear with a powerful truck has told you that shorties are a waste of money and do not benefit your power output.
Make up your mind on what info you are asking for, you're contradicting yourself. You seem like one who is gonna do whatever they think will work so have fun wasting money.
After reading the first couple posts I was getting entertained then towards the end I noticed how much time I wasted reading it all and now im starting to regret it.
