skewing the dyno??
What brand 10" dyno mufflers was it that you were looking at that you couldn't get?
I don’t remember now. They were hospital rated or something like that.
They were 10 in and 10 out. Couldn’t by the pipe either
They had nothing in 8 inch for pipe but I later found out if the mufflers had an application like earth moving equipment or OTR trucks you weren’t getting any muffler bigger than 6 inches without a PO that showed your company and end use.
That and other stuff like certain hoses used in heavy industries and such.
They were protecting certain industries to keep them from going without if the supply chain got worse than it was.
Oil and air filters was another. Once you got to a certain size if you didn’t fit the industry you didn’t get them.
Edit: I forgot to mention getting the pumps was a giant mother too. By the time I knew I needed the pumps you had to wait because nothing was in inventory and they were building them to order.
They had a shortage of seals and junk like that. I needed two pumps. I was told at one point they were only building pumps for standing customers.
I even tried to find a standing customer that would put my pumps on their orders. Didn’t happen.
