    i am running JBA on mine and i am happy with them i got their stanless ones, came with decent hardware...wished i would have upgraded my gaskets though. If you keep your stock Y pipe your ot improving much thats the weakest link in the system

    My main reason to replace wasn't for gaining alot.... my stock manifolds were all cracked and leaking... shorties where the same price as stock manifolds so that's what I opted for.

    Had a question on you flowtech headers. I purchased two sets of flowtech headers. Shorty black painted and Shorty Ceramic coated. But the flange looks different on each header

    So Andrew 89/98, the flange on the ceramic headers are about what mine looked like, but waaaaaaaaaaay shittier. The flange itself was about the same thickness but the actual sealing flange around the port was a mangled welded mess, leaked all the time. Those black painted ones you have there have a thicker flange by the looks and should avoid distorting when tightening.

    It also looks like the ports are different shapes on both headers, depending on which one you choose and which cylinder head you have you could have problems I bet. Which is yet another reason headers can suck, not necessarily always suck but could suck

    That's why it pays to spend a little time mounting headers, get a good matching flange, lock bolts, ball flanges for collectors and a flex pipe after the y-pipe
    Best of luck to anyone running them

    EDIT: Also, if I had pics I would have done comparison shots like what you have. Makes discussing things far simpler

    Yes the same thing I said, they are both flowtech and I figured they'd be identical other then the coating. I'm waiting on a response from Holley. The rep said they should be the same other then the coating but was not positive and would get back to me.

    The black headers flange is flat from end to end and thicker. The ceramic headers flange is raised on the exhaust port areas, making me think this will leak being the surface is only 1/4. Is this normal was my question but forgot to put that in there lol... image.jpg

    I just got done installing JBA shorty headers with the ceramic coating on my '98 V6. So recently I haven't even driven it yet, just started it up to check for leaks.
    On both sides I had to enlarge the rear most hole for proper alignment. Getting the EGR tube off the original manifold was a pain as was the flanges that mate with the crossover.
