Could anyone tell me the part number for the One chamber flows for my 90 LX?? Will they replace the same spot that my 40 series are in, or are they a different size? And what mods need to be done to make them fit if they are different?
single chamber flows wont fit in the same spot. they are about half the size and dont have the offset inlet/outlet. any competent welder/muffler place will be able to install them.
