    Does anyone have any? I was looking at the afterburners but there aren't many applications yet. They are a lot cheaper than thorley which is what i was looking at, does anyone know if they are good?

    I just installed a set of Flowtech's on my truck.. easy to install.. they cleared the starter so no interference anywhere. I'm happy with them.. even the performance gain is noticable on my tired 305 engine..
    Plus I was happy with the price... I don't remember headers being so much.. I paid $99 for mine.. Black painted.

    I have Ceramic Flowtechs...they fit well, clear everything, plugs are ok to get to, very few gasket leaks over the past 3 yrs...overall I'm pretty satisfied...the coating is holding up pretty good also...got a bit of rust where they got "rock rash" from these county roads I run, but nothing very major...pretty cheap also...JD

    I'm at 10th and Plum....10 miles from nowhere, and Plum out in the sticks....Stuck?...Hell no..I still got some gas left..

    Which model of their headers do y'all have? There were several when I went to their site.

    I just put a pair of the ceramic coated Flowtechs on my 350. Ordered them from Summit. I also bought the copper gaskets from Summit. I have a small leak in mine that I can't seem to get rid of.

    The Afterburners seem pretty good for Flow Techs, since I hate these regular FT headers! The ones I installed on an 86 short bed I had once fit like SH!T! They hit the spring bolts on the shackles. I paid like 75.00 for those and tried to bend them to fit. They bent the flange and I was out 75.00. So I got Hedman Hedders. Perfect for small blocks. On my two one tons with 454's, I run Hedman on both of them. Very good headers for these trucks. If money were no issue, I would try the Thorleys or L&L Products.

    Take a look at my reply to SAVAGE1 on Dynomax vs Flowtech. No interference at all w/Flowtech & they work.
