Morgan-McClure X Pipe Exhaust Sound Test: "Stock" LS Swap Longtube Headers (Science of Sound Pt1)
To start comparing quotes and simplify insurance-buying, check out Policygenius: .
Thanks to Policygenius for sponsoring this video!
To kick off the science of sound test series we hook up the real deal #4 Kodak 2001 Winston Cup car exhaust to our 6.2 LS powered 1972 Monte Carlo. The car has standard Speed Engineering LS swap longitude headers on it currently (which are not ideal for this exhaust setup). We hook it up and see how it sounds compared to the Dr Gas x pipe boom tube kit that has been on the car!
Following this video you will get to hear what this exhaust sounds like on the road with custom built equal length headers with properly configured 4-2-1 tri y collectors!

    I think the old school term for same length header tubes are called Extractors. You seem to be on the right path for what your seeking and should sound So Sweet ! Being in Race City U.S.A. is helpful on your availability for knowledge and damn cool NASCAR parts . Keep up the Good work.

    Man how cool would it be to get Gerald Rinehart on one of these exhaust comparison episodes? After 2000 he was definitely one of the key players that developed all these exhausts for Nascar and Indy. I don't know how in depth he would go into explaining the technology behind them but he's definitely the guy who would know the "how's" and "why's of how all of them works.

    • Wooley689

      Yes, that would be a great one to see.

    Your not crazy it is interesting to hear and see the process you go through to get what you want! Good job Mitchell!

    • Stapleton42

      Thanks man! More to come!

    Your new headers SHOULD make more power, or at least a smoother power delivery, because they will be closer to the “perfect” setup (i.e., GT40) with appropriate pulse scavenging. I can’t wait to hear the finished product and see if you feel any power difference.

    I have dealt with quite a few SB2s, and they just sound different. They have a tone that no other engine has. I dont think youll achieve the exact late 90s nascar sound with an LS but it should sound great either way.

    • Heidarz

      @Stapleton42 isn’t the small block ford firing order you’re referring to the Cleveland & EFI Windsor firing order, not the traditional 289 & 302 firing order?

      @Stapleton42 I remember back in the early 90's in the same race at talladega Dale's car was only turning around 6800 rpm and Davey's thunderbird was turning around 7100 rpm

    • Slopoke

      @Austin Wilson you can't copy people is the thing. You could say the same thing about the "tried and true" symmetrical port ford cylinder heads, that the ls uses right? They are all air pumps and I love em all.

    • Austin Wilson
      Austin Wilson

      ​@Slopoke true I'm just trying bring light to something some gear heads probably don't realize. that the heart beat for many great v8s is the tried and true 18436572 even despite how bizarre ford got with their numbering sequence the March to the same beat as a gm or Mopar. I do find it odd as to why ford would run counter clockwise on the distributor I guess maybe a holdover from the flathead days?

    • Slopoke

      @Austin Wilson we can get about as crazy as you want nowaday but I was just stating in general.

    This is really fascinating content! I can't wait to hear it after you finish your headers. There's nothing like the quest to achieve the perfect exhaust notes you desire.🏁

    The sounds that come from a car can make or break a build. I love the sounds you are going for they happen to be the same ones i grew up hearing and growing to love hot rods.

    I am completely sold on the black steel wheels over the old torque thrusts, it looks so aggressive. I worked in an exaust shop for a few years, and it was always fun to experiment. I got to where I could tell what someone wanted by talking with them for 2 minutes. -25 year olds usually want it as loud as possible regardless of how it sounds. Most older guys wanted a good sound, but still able to talk. One day this 70 year old hippie looking dude wanted me to put true duals, no h or x, with straight pipes on a 2000 Chevy blazer. It sounded aweful but he loved it...... Some people like jass, some people like heavy metal. Keep going you will get the sound you want.

    I think 180° headers with that x pipe would sound amazing. I'm a third generation dirt track racer and I've work at a few of the race tracks in my home town. Drag racing and sand drags, asphalt/dirt oval, grip racing and drifting. I've seen MANY different headers and home made headers. Good luck on your quest for that iconic sound.

  • John

    Definitely want to learn more about the affects of equal length exhaust vs not equal length!

    • Cory Klabunde
      Cory Klabunde

      I realize this channel doesn’t touch on imports but turbo Subarus have an unequal length manifold that merges before the up pipe going to the turbo which gives it the deep rumble sound which is why most Subaru owners love them. You typically only go equal length for performance for far better airflow but it really diminishes the rumble sound. Just my .02

    • Stapleton42

      You are in the right place!

    To me that is absolutely worth the time and cutting up a set of headers to make it fit properly, and I love those Monte Carlo's.

    I love these exhaust videos and exhaust testing. I could do stuff like this all day long

    I'm excited to see the side by side of the sound difference. Maybe it's time for equal length headers here also. 🤔

  • Jeremiah Johnson
    Jeremiah Johnson

    I am sure you can tell the sound of a healthy car with an exhaust and when it is hurt easier with an exhaust. MONTE sounds nasty. I love how logan backed up when you snapped it. Perfect noises. Sorry i missed the live stream it looked fun for interaction with you guys.

    • Stapleton42

      thanks man we will schedule the next one!

  • Clancy Allard
    Clancy Allard

    Id love to see you make a custom equal length 8 into one exhaust! That should give you a really nice whine like an indy car or flat plane crank, especially under boost, i bet itd sound insane, now to go even more balls to the wall insane, you could throw one of the smaller boomtubes at the end like maybe one of the new old stock tubes you got would work pretty awesome. I guarantee if you did that setup it'd be the most unique sounding car around especially under boost with that supercharger whine trickled in. That setup would make an AMAZING dyno pull video!

    Firing order has a huge effect on sound too so it still may sound “off” I’m very Curious how this is going to turn out

    • Stapleton42

      The firing order of an LS is the same as a 351 Ford so in theory it would resemble the Ford cup cars of the era sound wise

  • Mark Miller

    Sounds great to me, has a healthy bark to it to begin with. Appreciate your determination to get this project to work, it will satisfy your inherent curiosity and make good noise! The Monte Carlo will be even more badass than it already is. Have done stuff like this before with my bikes and cars, my Chrysler 300C hemi has my R/T Challenger exhaust system on it, sounds great and works nicely! Right there with you & Logan, you both rock bigtime! Thank you for a cool video!

    This is awesome ! I built a car ten years ago , wanted it to sound a certain way , did my research and brought all the stuff to do it how I wanted ….. gave up took the easy route and have regretted it ever since …… don’t give up it will sound killer !

    • Stapleton42

      Thank you Scott!

    Man I’m totally excited to hear what this beast sounds like after it’s all said and done.

    I think once the headers get done this thing will sound like it should. It’s pretty close right now. The more you see the science in exhaust technology that the teams in the 90’s thought of it’s amazing the detail they go into. I don’t know if you caught Dale Jr’s Podcast this week they actually talked about the Morgan McClure exhaust and how they were leaking air around the plate. I want to say I heard Dale Jr said it made like 10 HP from leaking the air. Also learned how other teams were leaking air on the intake plug fake plugs in the intake

    You had me at the Escalade, but I have to say thought I was all in when you started going through the Nascar history and showing the classic stock car stuff, but now you 1000% have my attention. I have always had this same motivation for making cars and trucks sound cool and I am as curious as you are about the science and history of what made the classic Nascar sound and when you mentioned 180 degree headers I knew we were destined to be best friends lol. Keep up the awesome content and I am along for the ride!!!

    What you’re doing is pretty cool! I’m curious to see how it goes. I’m running circle track headers on my G-body, because they’re actually the best fitting headers I’ve seen. I had to remove the AC box, but it was well worth it

    Mitchell, FANTASTIC video! Think about naming this video series "Six Million Dollar Boom Tubes". Because you are making them, stronger, faster, better sounding!

    It sounded pretty darn good to me. the flow of the engine itself won't be the exact same as an sb2. having the same firing order and the tuned length headers with the extra tune of the 180 dg headers, I think it'll be close enough.

    it's starting to sound a bit better really interested to see what it will sound like in the end the psuedo 180 degree header part you mentioned as well is going to be neat i have saw some corvette videos on youtube with 180 degree headers but not with boom tubes

    This escalated quickly! I can completely understand. Excited to see/hear the finished product. 🤘

  • John Thomas
    John Thomas

    Tube volume is as important as tube length. Also tube size to speed up/slow down exhaust flow (to a point and would need to be optimized by R&D). Everything is a compromise unless you are building pulling truck headers.

  • MOE

    I am with Logan on this one. It may not be the sound you are searching for but it is unique and very angry (aggressive?) sounding. Great idle warble. It would be so interesting to test which one of your vintage exhausts produces the most power for your setup.

  • John Snow
    John Snow

    Build your boom tubes with oval piping like ice T has for extra ground clearance but keeping the diameter for flow. U can gain over a inch of ground clearance with the oval 3" vs the round 3" pipes.

    • Stapleton42

      They will be oval. There’s a whole stack of oval bends from Boyce on that cart

  • 1987FX16

    I think the #3 boom tube will give it the high pitch scream you want. The smaller height makes the deep sound waves have to bounce around more than the shorter high pitch sound waves. The high pitch will be filtered less because it's physically narrower so it moves through way easier than the physically taller sound waves.

  • Rudy Hollis

    We ran a Dr. Gas X pipe on my oval track car with Dynamax 3.5" race bullet mufflers and it was the best sounding oval track car I ever heard. We ran a different (larger) track one Sunday and won the race and afterwards alot of the super late model guys came up to wanting to know how many rpm's we where turning and how'd my car have that turbo sound!!!!

    Sounds freakin awesome! Sounds exactly like a 90s era nascar stock car! Just like one of the old luminas! I think Dale Earnhardt would be proud for sure lol! Nice freaking ride Stapleton! Great video as always my friend!

    • Stapleton42

      @John Snow I guess you will just have to see when its done. It wont idle like a cup car (I don't expect it to) but it WILL have that melodic howl when the car is under load. That is the point of the experiment. Idle sound is irrelevant.

    • John Snow
      John Snow

      @Stapleton42 without a cup car camshaft with the proper lobe seperation and duration everything your doing with the headers is a waste of money, time, and energy. The cylinders won't fire properly when the cam is designed for a supercharged motor not a na motor.

    • Stapleton42

      thanks man!!

  • Brian Bartlett

    Just out of curiosity, it would interesting to hear what would sound like behind the 632. Depending what the compression ratio and cam specs are for it.

    • Stapleton42

      We will eventually test that too!

    Still sounded awesome. Especially when you stomped on it! I saw that one coming.

    I believe you're doing everything exactly correct man... about to cut my headers up to make them equal length because I'm too poor to buy the correct ones LOL. Just because you don't have money don't mean you can't go have fun... Keep up the awesome work guys

    It may not be where you want it yet, but I know you'll get it there. Also was back watching the original x-pipe video and I kinda miss seeing the escalade get down. I know its a hastle to mess with but it'd be cool to see it back out.

  • Don Natalie Lucas Heimbigner
    Don Natalie Lucas Heimbigner

    Assuming that the "original" headers make more power, like they should, it only shows how horrid manifolds are. It will be incredible once you get your new headers put together. It may not make more power, although I bet you would see some on a chassis dyno, but it will run smoother, which will increase the lifespan of the engine.

    The exhaust note your vehicle makes is very important. My 94 sierra is on exhaust setup #2 since the 5.3 swap. First setup sounded great at idle, but sounded like dog crap at part throttle and it drove me crazy. Made a muffler change and now its perfect

    I smell where you're stepping in Mitchell and I'm here for it. As soon as this video started I had a feeling the boom tubes wouldn't sound any different without the headers having equal length. That car is going to sound so badass when you're done. I'm patiently waiting.

    Equal length headers in the future are definitely another comparison. Should sound perfect then. A full equal length exhaust with that x pipe should get you the sound you're looking for.
