    Many things to consider and I agree with you. Good point. I guess we got carried away lol.

    Yep Manifolds are pricey and even more so if you get them coated so they stay nice looking.
    Still less trouble than tubes but rob some power. So let’s throw the new headman elite shorty
    pipes in the mix. Anyone here have experience with them?

    Shorties might be the way to go for those who dont like the loss of ground clearance with headers. I can't believe the shorties would be any worse for horsepower than the manifolds. Surely lighter, but possibly still all the drawbacks of headers, burned plug wires,loosening bolts etc.

    Just finished putting a 400 stroked BB into a 76 Aspen R/T. HP exhausts cost $150.00 and the exhaust shop cost us $120.00 to run them into the mufflers. So it is always up to the owner to decide. What do you want is the first thing to decide.

      I think you got a helluva good deal on your manifolds. I haven't seen any here for anywhere near that price. There would be no need whatever to repop them if they were available everywhere for that price, they are repoped because they aren't.
      Edit: so repops are on sale for $460, normally $500.
      Re-edit: so headers- lighter, cheaper, more power, less under-hood heat. Your choice. Note ,i have one mopar big block with headers, and one with manifolds, and both are exactly the way i want them. I am not in favor of either, i am in favor of making your car the way you want it!

        I have found that there are a lot of HP exhaust around, but finding them is sometimes hard. It took me awhile to be accepted in my area by MOPAR guys. It takes alittle to be accepted if you are a new person in any area. Now they know me, accept me, I find good deals. The exhausts I got took me hours to clean. But worth it.

        Yep, no complaints about the headers, other than the peeling paint that powdered off and grubbed up my spark plug socks. No leaks, no clearance problems. They just look crappy. I have to pull the engine in the spring to replace a leaky frost plug. l might just replace them. The cost of hp manifolds and the weight puts me off as well as the hp loss. Thanks for all the replies

          For what it is worth, on a header test on engine masters, they compared coated verses uncoated. No change in power, but the temperature difference was staggering! Something like 200° verses 800°. Coated will look better and last longer. Worth the extra cost in my opinion.

            That's a huge difference. I haven’t looked into it yet, but is this a factory coating or something a shop can do

            I just put my 68 road runner manifolds on the scale
            RH is 17 lbs
            LH is 19 lbs

            PS I turned down $400 about 10 years ago--some day they will be going on my 67 R/T

            As others have said, there's benefits to both - but I can't stress this enough here.
            If you choose headers, great - but spend the money to get GOOD ones and the truly
            good fitting, well made quality pieces are well-known.
            It's TTI or it's Doug's, pretty much.
            For the love of all that is holy, don't go cheap on this. Life with 2nd tier headers generates
            annoying situations that anyone shouldn't have to even worry about, but will.
