Will a Boxster S Muffler fit on a Standard Boxster?

[Boxtaboy]

An 02 S muffler will fit your 02 base with no issues. The muffer is exactly the same as yours except for the dual tip welded on the end of it.

I used to have a rattle at idle on my muffler too, and at first thought that the muffler had a loose piece inside it, but later traced it to a loose clamp that connects a U-pipe from the cat to the muffler. If I pulled on the u-pipe, I could tell that it was loose and would move. After fixing that, no more rattle.
