    I have a 99 Z71 with a 5.3, k&n intake and a y pipe and duals. Will headers, true duals with an H pipe with stock converters make a big sound difference? Which headers make the biggest hp gain in 1-2 rpm long tube or shorty? Will high flow converters hurt the low end power because of less backpressure?
    Any help appreciated.

    Hey, Welcome to the site! You will not see and added HP from shorty headers. LT's are the way to go. I have true duals on my truch with Magnaflow HFC's with Flowmasters. In my opinion if you loose any lowend trq it will not be enough to notice. :glasses: The next mod you should consider is a custom tune eithe Wheatley or Nelson. I will be getting mine from Nelson when the time comes
