are expansion chambers for RD350 and RD400 interchangeable?? If not, are the hanger connections different?
Almost interchangeable. C-C of the flange studs is slightly higher om the 400, and the hangers may differ a little bit as well. Easily fixed with a round file or Dremel anyway
hangers and flanges as mentioned. can be made to work.
Yep, just some mods and you can make it work.
thanks for the info! ;D
