    So I ran across these headers while researching and they seem promising to me but wondered if anyone on here has ever tried them or what the general consensus is on them.

    They make both long tube and shorty headers.

    I know before anyone posts that the general thought is long tubes or don't bother.

    However after looking at there short headers they seem to produce decent numbers according to an independent dyno.

    These are the ones I was looking at...
    http://jbaheaders.com/detail_shortyV.asp?id=1850S-2JT

    They offer them in raw stainless or silver ceramic or titanium ceramic.

    I would opt for one of the 2 ceramic coatings.

    They call these Cat4ward headers and they mount up to the stock cats and Y-pipe which is convenient. My thoughts on long tubes are that they may produce more power in the higher RPM range but I have a long body that is daily driven. It is certainly not a race car so it rarely sees high RPM.

    Also I am concerned with the ground clearance of long tubes and 4/6 drop.

    Plus the added cost of a different Y-pipe with long tubes.

    I found this article from an independent website that installed the JBA shortys on a 2008 5.3L pickup...
    https://www.offroadxtreme.com/engin...ust-system-give-this-5-3l-v8-a-power-upgrade/

    They dynoed it before and after the install of the shorty headers and aftermarket muffler and the results were pretty impressive I thought.

    "When we ran the 2008 5.3-liter V8 Chevy Extra Cab pickup on the dyno before the installation, it recorded a peak hp rating of 246.1 at 5,370 rpm and peak torque of 250.1 at 5,100 rpm.

    The after-installation run on the dyno showed 260.9 peak hp at 5,380 rpm and peak torque output of 277.7 at 4,690 rpm. That is a gain of 14.7 peak hp and 27.6 lb-ft of peak torque. However, as with any truck application, we’re more interested in gains in the low- and mid-range. The dyno chart below reveals healthy gains in these areas as high as 45 lb-ft of torque at the critical 2,500 rpm point. A power gain such as this down low will substantially help the truck’s acceleration and improve performance during normal driving conditions."

    As with anything the peak numbers are one thing but the power curve and where you pickup gains is also very important.

    They don't mention any tuning so I wonder what kind of gains might be had above their numbers with a proper tune.

    Any way... let the discussion begin.

    one thing I have never understood is why they don't make headers with a full size mount-bracket, they make them bare minimum size to cover the holes, then they just leak constantly

    I saw where JBA was a PerTronix company.

    Further research...

    PerTronix website says...

    Under the brand names Patriot Exhaust, Smithy mufflers, and VeraFlow mufflers, PerTronix supplies the Street Rod and Muscle Car markets with headers, mufflers, side pipes and do-it-yourself header components primarily through performance warehouse distributors. Doug’s Headers includes many header applications for muscle cars, SUVS, trucks and motorhomes.

    http://pertronix.com/prod/ex/default.aspx

    Not sure what all that means but thought I would share.

    I put the patriot's on my nbs, they leaked, they cracked, had them welded they cracked again, went back to oem exhaust. had the TRD's on my 4runner they cracked, had them repaired under warranty maybe 10 times, finally after the warranty was on it's last leg they gave me new ones that had a redesign with some kind of spring mechanism inside them, they didn't break again, but I rolled the 4runner and totaled it sometime later. I guess I need the ones they put on race cars I'm to rough on stuff

    Awfully quiet in here...

    I figured @Rocket Man and some of the other high performance aficionados would chime in.

    I now @swathdiver is away for a bit... still praying for him.

    I would definitely be interested in hearing your assessment of them if you do get them.

    I think I want them pretty bad... lol
