6.2L LS Equal Length Headers with NASCAR Tri Y Collectors! Equal vs Unequal (Science of Sound Pt2)

In the last video we sound tested the Morgan-McClure x pipe boom tube exhaust with the regular speed engineering LS swap headers on the car and it did not sound right. I theorized the massively unequal length headers were the culprit for the less than desirable raspy sound. I have spent the last month or so of my free time custom fabricating equal length headers by cutting up the old ones! The spread from longest to shortest primary is less than 1.5" across all 8 cylinders. They feed into used NASCAR tri Y (4-2-1) collectors into the exact same Kodak car x pipe boom tube exhaust from before. Will it change the sound? Lets find out!

Did the results surprise you? In the next part of this science experiment we will get the car out on the road and sound test boom tube exits vs standard oval tube exit connected to the same x pipe! More fabrication to be done 💪🏻 Boom tube shirt link Stapletonautoworks.com

[@chrisbali5246]

Nice and clean sound.Thanks for posting you're hard work!

[@Scooty_scoob]

Sounds awesome making or modifying headers is a pain. At least with the tools I have. When I saw the first video of this series I knew that #4 xpipe was the way. I made something kind of similar using 2 180° bends and added the crossover tubes. Had to modify some Ram long tube since no one make them for Dakotas. Hopefully it sounds similar to your set but a little quieter. One last thing you should look up david vizard. He was written tons of books and hotrod articles. He also has a youtube channel There is an article from one of his books on headers and exhaust. It covers primary tube diameter and length. Plus secondary diameter and length. According to David the primary length is not too important. Just try to prevent all exhaust pulses for entering the collector all at one time. According to David the secondary is where all the magic happens. He give charts based on cfm flow of the exhaust port and approximate hp or tq. I can't find the article right now but if I stumble on it again I'll link it.

2 months later and I just saw this. I don't know how to weld or fabricate, but I really appreciate the effort you went through to satisfy yourself. That's the stuff that makes life enjoyable. There was a noticeable difference that will definitely pay your emotions every time you drive it. Congratulations!

[@DaveWrightKB9MNM]

You're not crazy. You're dedicated. I was that way when I was trying to make a Quick Release for my Steering wheel base. Finally gave up, only because I was tired of it dragging on and I couldnt think straight.

The sound you are going for is one I fell in love with when I was 4 working with my dad on my uncles race cars. I will use these videos for reference on what to do and I showed my dad and he wants to change his GTO exhaust because of this video. Thank you for the info and All the fun I had watching you guys.

[@Stapleton42]

Thanks man!!

[@KaminerRacing]

Man well done on the equal length headers. I have owned a few off the shelf "equal length" headers but watching you explain how your thought process went into the final product made perfect sense to me. The sound difference to the casual person probably was nothing big but what a huge difference it actually made. The up and down was so crisp and clean now. Can't wait to hear it on the dyno or out on the road under some load. Side bar, how about that power stance at 24:52 haha Keep up the awesome work, excited to see the rest of this series and get even more ideas about building sound profiles for different engine combinations.

I gotta say I love the dedication here and it was not only entertaining but educational and I vibe with it.

[@Stapleton42]

[@Mart77]

7:05 - yep i'm still following and having same thoughts, main idea is to pair cylinders that are as far apart as possible in the firing order. Gases going past the "emptiest" tube will scavenge a vacuum in it, helping exhaust to have better flow

[@jamiehess6443]

I don't care what anybody says, your attention to detail is astounding. I understand that it seems like a boring thing to probably most of the people but I find it very intriguing. If you're going to do it, you might as well do it right, and as long as it takes. I love the other videos on the NASCAR history, but I kind of miss the build videos. Can't wait to see you tear into Logan's rod. P.S. you are not crazy!

[@Andrewlang90]

The equal length sounds much cleaner. Without that rasp of the unequal length, it’s just a cleaner sound to it. Love it, can’t wait to hear it on the road under load

I was a pipefitter so I've had to make things fit. Usually the pipe size was bigger. If you think all this was worth it than it was. You learned so much. The welding looked good. I would like to see you "walk the cup". Can I suggest using a drill to sharpen the tungsten. Also sharpen both ends so you can flip it over if you don't booger it up too bad. Good job man.

[@darrenobrien7667]

I'm watching your welding sequence and seeing you clean/sharpen the tungsten every time you dipped it made me want to share something I do to prevent that. I tend to break my tungstens into 3 or 4 pieces when I pull them out of the package and then keep a half dozen of them sharpened up. That way I don't have to get up when I dip. I can just swap tungsten and keep on rocking. Saves having to reposition yourself and get comfortable again. I find it is not just a time saver but also saves a lot of frustration getting set back up after sharpening.

[@Stapleton42]

Thats a good idea

I once added a loop downstream of the passenger side headers on a GMT800 to try to equal out the length of the pipes prior to coming together with an X-pipe. Back in 2005 it was the best sounding GMT800 out there. I love videos like this because most people don't understand it until they see it. In my case, people thought I was nuts that I even had the idea until they heard the truck.

Great job on your part building those headers Mitchell. Back in the day my "go to" equal length headers were Mickey Thompson Super Scavenger Headers. They had exact equal length primaries that went into a square tube collector then terminated into a flange. Those were the best sounding and broad power producing headers and if you had a set you were the king of sound on the street even with mufflers. The large square collector produced a sound all in itself, nothing else compared. If/when you do look them up, I will have for sure dated myself, yes I'm an old school street racer and had no regrets then or now. I wish I could find a set or two of those headers for my next project. After watching you put all that effort into building yours, maybe I'll make a set of the Super Scavengers for my latest build🤔💡 Keep on with the good work and content.
