    Do or Are Shorty Headers better than the stock manifolds on a 2004 GMC Sierra with a 5.3 in it?

    Re: Shorty headers vs stock manifolds

    go longtubes or keep your manifolds, shorties may offer little gains but are a headache in my opinion. Ive only had mine a month or two and Im already planning to ditch them next time I get the cash for some thorleys. The flanges on my edelbrocks never sealed properly and Im having to get them welded to the downpipe for the time being.

    On the 99+ trucks, no, shorties will offer no improvement over the stock exhaust manifolds.

    You put headers on a truck for a different sound?

    Re: Shorty headers vs stock manifolds

    I have some JBA shorties on my truck I have had them on since about 15k miles I now have 62K miles and I haven't had any problems with them, no leaks, and I haven't had to do anything to them. Longtubes can give you more power but depending on emissions laws they are not C.A.R.B legal. I used to live in Dallas but I can't remember how strict the laws are there so I would check on that. I got more power out of mine, yeah it's not much only like 10 or 15hp but's it does make a difference and it did help with mileage

    JBA's use a cone shaped flow enhancer (I have heard them called merge bullets before) where all 4 pipes merge at the collector for better scavenging which is the main reason they make better power over other shorties, they also cost about $700 if you want ceramic coating so unless you have to go with shorties (C.A.R.B. legality reasons, etc) go with longtubes, you can snag a set of ceramic coated hooker super comps or thorley tri-y's for less than that.
    Only reason I got shorties was because my manifolds had warped and needed to be replaced.

    wow! they're a lot cheaper for the NNBS trucks

    stainless unfinished for my 6.0 is $500+ ceramic start around $700

    Re: Shorty headers vs stock manifolds

    Yeah the JBA shorties are probably the best ones I don't remember how I paid for mine but it wasn't 700 I just got the stainless steal if I remember right they were 350.00 but I did get them from a place I already had bought a bunch of stuff from so I know I did get a discount.

    Re: Shorty headers vs stock manifolds

    Okay that info does help me a bit. I am still undecided as of yet. So here is my next question regarding the long tube headers... I have heard that if you put the long tube headers on your truck you lose low end torque. Is this true? And for an everyday driver would it be too much of a loss?

    Re: Shorty headers vs stock manifolds

    Longtubes are supposed to boost the low end power and response. At least that's what I've been taught.

    As for the shorties being better than stock manifolds. Yes, any shorty is going to be better than what is on there now. The stock manifolds have come a long way, but they are not a shorty header made out of cast iron, not even close.

    Go with thorley tri-y's you'll see a noticeable jump in low end torque, thats what they are designed for

    Re: Shorty headers vs stock manifolds

    :jacked: tex2500, how is the finish holding up on your Ti-Tech's? My Ceramics were good for about a year and then the flange started to rust a little bit. The pipes are good, just the flange has some rust.


    I dont have really good photos of the flange



    This is the best view I have. (I was installing my BlackBear Performance PCM in this pic)

    Re: Shorty headers vs stock manifolds

    My Ti-tech finished Edelbrocks are less than a year old and the tubes are freckled with rust spots. It's just surface cosmetic rust and it's most likely due to how close I'm parked to the ocean. I'm fine with it since what things look like under the hood matters very little to me, but had I known that was going to happen so fast I would have considered going stainless or opting for some JBA's.

    Re: Shorty headers vs stock manifolds

    5.7JWL, my headers are holding up good but that doesnt mean much as they have only been on there for two months. My real problem is that they leak real bad, I think the downpipe flange is bent but Im not sure. Ive had a lot of problems getting these to work.

    Same here (except the ocean part, and it's not my tubes, just the flanges). I went by Summit ( I live about 15min. from the one here in Ga.) and told/showed them the headers and they said they would give me another set. I didn't feel like taking these back off. They are direct bolt on, but it's not like your making a peanut butter and jelly sandwhich. The rust has not gotten any worse in the last year so I'm OK with it. If it were a show truck, you bet your a$$ I'd have a new set on there.

    Is it both flanges? When I put mine on, I got them as tight as I could at the "collector" ( there is the one bolt on top that is a PITA) flange but I still ended up going by a muffler shop and paying the guy $10 to tighten them down after locating the leak. It was the Pass. side.
