NASCAR Boom Tube Exhaust Types Explained: Different Setups = Different Sounds! (REAL Parts)

Watch on YouTube

What happens here

The video moves on to a detailed explanation of Tri-Y headers, distinct from traditional H-pipes or X-pipes. Tri-Y headers strategically group opposing cylinders in the firing order within their primary collectors. This precise pairing ensures that exhaust pulses align optimally when they meet in the secondary collectors, resulting in a smoother and more efficient flow. This design helps to reduce back pressure and minimize reversion, ultimately creating a higher-pitched sound. The presenter emphasizes that the specific firing order of the engine is critical for Tri-Y headers to function effectively. The video is concluded by encouraging viewers to subscribe to the channel for more content and to check out their merchandise.

Goal: Explain the design and benefits of Tri-Y headers and promote engagement.

we'll save that for later later in the video oh and it is worth noting that these pipes in here are passed through i don't know why i talked to the guy that worked for morgan mcclure who built this and he said it was just a brace and they stopped doing it because these wells are cracking okay there's no way that it was just abrasive air is coming through there yeah if it's just a brace then why are these drilled out in here so air can go through i would theorize that this is almost like an h-pipe for the x-pipe so it bleeds off or equalizes a little bit of pressure on both sides of the x to let the x do its job more efficiently i don't know i'm not a physicist i'm just somebody who thinks about air going through a pipe and what we're going to do because that one is so sacred is we're going to recreate it everything about it spot for spot thanks to voice industries slash aed i didn't know that's okay i don't know if you can actually buy these i think they found them buried in the warehouse because i gave them the part number that was on there so those are like legitimate real deal new old stock this is what they would have looked like whenever you know whoever morgan mcclure rcr dei if they bought these and built them they come like this and then make them like that they did come like that then morgan mcclure did not use the supplied um transition piece they made their own all these oval bends you can get from boyce 2. they got part numbers stamped right on them the same part numbers actually that are stamped on the pieces from 2001 are still active and being produced today so all this stuff you can still get so if you find anything find a boom tube or you just want to make the whatever you want out of ovals boyce has you covered oh if you're wondering what this big block is for it is for that suburban we're gonna do a sound experiment with this thing and that 632 it's a 10.35 liter big block conventional firing order same as a you know the small block cop cars would have been in the 90s we're going to make as close to equal length primary headers for it as possible and we got profab to make some try uh collectors and it's going to have the x pipe and the side x's and stuff see if we can get a big block like this to howl like the restricted play cards did back then maybe you know it's not going to sound just like that because it's a much bigger engine but um it won't sound like papi's bracket car and number five probably this truck series exhaust i'm really…
