Will a 01 boxster S exhaust muffler bolt right onto my 02 base boxster.

I have 01, non-s. Purchased the car with B&B muffler. ran great and had great sound. little drone at 2600 to 3000. muffler baffle broke, replaced it with 02 S muffler. all mounting points OK.
the S muffler is quiet and no drone.

Yes, just like everyone has said... Straight bolt on, mounting points are the same.

As far as I know, for those years, 00-02, they Base and S are interchangeable. The only difference being single oval tip vs twin tip. And for 03-04, the difference between the base and S is that the (single and twin) tips are removable.
