I wouldn't , and i have them. Not saying they are bad but between the cost of them and what you will pay in labor to replace the factory setup that sounds like has nothing wrong with it it just doesn't make sense to me ??? Your not really into any more labor down the road should you decide to do them later. When they do start leaking , then go ahead. Now , if spending the extra money doesn't really hurt you right now and you plan on keeping the truck for awhile then by all means throw some bellowed up-pipes on there today !
