Homemade ler?
Anyone ever done it?
Im thinking of taking a 2 1/4" or 2 1/2" pipe, drilling a ton of holes through it, wrapping it with something, and inserting it into a bigger pipe, like 3". Then crush the ends of the 3" pipe down on the smaller pipe or something, and welding it.
Not sure what I would wrap it with though, fiberglass header wrap, or that cheap exhaust wrap at autozoo?
