Morgan-McClure X Pipe Exhaust Sound Test: "Stock" LS Swap Longtube Headers (Science of Sound Pt1)

Watch on YouTube

What happens here

The presenter reaffirms that the current Speed Engineering headers, with their non-equal length primaries and "stamped" collectors, are the primary reason for the unsatisfactory exhaust sound. He shows different types of headers, including Hooker Headers (Hooker variant), which also had fitment issues with the starter. He then finds a set of ARCA race car headers, likely for a Robert Yates spec engine. These headers are promising because they feature near-equal length primaries and Tri-Y collectors, which are known to improve sound characteristics. He notes that while these headers look much better acoustically, they will still have significant fitment issues with the LS engine's starter location and the Monte Carlo's frame.

Goal: Identify the specific acoustical issues with the current headers and acquire better ones for modification.

yours yours yours yours yours well we get packages and we bring them inside and then they end up staying right by the door you want more extra nonsense like that you can check out the stapleton 42x4 channel that's where you'll find that right now don't know what to do are you okay did you just funny bone yourself on ralph's butt yeah i think i caught that on camera too no i think we need to go to one of the uh youth parts places like circle track warehouse or sri or something and find some headers from an arca car and see if they'll let us return them if they don't fit or like i just want to test fit them to see how much they don't fit because they can be modified to fit if they're close like you know cut one primary tweak it a little bit you can do that but these i'm convinced that these headers are just not going to make the right sound no matter what you strap to it i just don't think it's going to work right the engine that i used to drive to classes with is connected to an exhaust that very possibly ran in the 2001 daytona 500 on a morgan mcclure kodak card yeah how weird is that i don't know but it was really cool that like you know when i cleaned those how dusty they were yeah did you see the dust blow out when you hit it no it was cool it'll be in the video yeah i hope so we'll get to see that okay i want to watch that phone video hear how that audio came out my ears hurt that was loud i didn't know you were gonna do that i was right at that exit when you did that i was pissed because i was like i thought you were getting in to turn it off and you weren't turning it off i don't know when i turned it on it still sounded exactly like it did before i'm like maybe it'll sound a little different if i just blip it like just to be able to tell if it's going to be any different did some digging around and actually found a set of headers from an arca car this video is brought to you by policy genius policy genius is your one stop shop to find and buy the insurance you need did you know one of the easiest ways to instantly save money is by reshopping your home and auto insurance using policy genius customers have saved an average of 1 250 a year for what they were paying for their old insurance policies reshopping and bundling your home and auto insurance with policy genius can save you money that you can use on your next car build or diy project around the house they do not sell your info to third parties they have thousands of five star reviews on google…
