well guys an hour ago i started my install of my flowtech LT's with there O/r x pipe. iT looks as if my day is gonna be a long one lol. I cant wait to hear this thing run after the headers and x pipe are installed compared to the stock exhaust manifolds and O/r h pipe.... Any thing i need to be especially aware of when I am installing these? Oh yeah IM not dropping the K memeber I am just gonna lift the motor up.
