I believe they are all interchangeable. You can compare part numbers here.
What years can I search for an exhaust that will fit my 87' TW200? I'm pretty sure it went unchanged for several years. Thanks!
all the header pipes are the same throughout all years, you can also use a stainless version from an XT or Serrow (forgot which) just needs 1/2" trimmed off the end. the only thing thats different with the rest of the exhaust is the lower frame mount is for the rear section on 01+ models
