looks like porsche would rather delete the cats on the headers than on the midpipes. i'd read that there is no power difference between the two iterations, but perhaps a weight savings? |
Just because someone says a part fits a Boxster it may not. In my experience if a part fits a Boxster & nothing else the part# starts with 986. If the part# starts with 996 it was used on 996's & may fit Boxsters since these cars were developed jointly to share parts to save costs. 996 exhaust manifolds don't fit Boxsters. I think any Boxster not required to have warmup cats for emissions laws (ROW) uses the 97-99 USA exhaust but I would have to check part#s to verify that.
