Well I have two questions. First, how long will these headers (hooker comp) last, I know that they will need to be replaced eventually, thats not a problem, but how long should they typically last under everyday driver conditions. Second, I seem to recall reading in Jegs that they came with a y-pipe for our cars, mine being an 84 LG4, am I right? Thanks in advance, and sorry in advance but i've been looking for the past couple of days for info here on Hooker Comp headers and I never really found any mention of them.
