Will a Boxster S Muffler fit on a Standard Boxster?

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.

Thanks Boxtsaboy,

I'll check the clamp. I was thinking it was the baffling inside the muffler because the exhaust tone alternates from sounding very nasally or froggy to sounding deep and smooth like a porsche should sound. I'm envisioning a piece of metal inside that's shifting changing the flow of air through the muffler. But even if it's just the clamp I'll still swap the muffler. It has about 80K miles fewer on it and it has the dual tips. And since I've already swapped out my headers and secondary cats with performance headers and secondary bypass pipes the muffler can be the only culprit left.

Hey Tim, yeah like said above, give the clamps a shot to get rid of the rattle...

I'm curious to your impressions of changing to the performance headers and bypass pipes. Would you please elaborate on your driving impressions with these new parts? Did you feel any power gains, or differences in how it performs?

I did notice a difference. It feels like I've gained some HP. Not a huge amount. Maybe 10-15 if I had to guess. The biggest difference is in sound. It's definitely louder but since I kept the stock muffler it's not so loud as to upset the neighbors. It sounds great (when my muffler isn't acting up) around 3K rpms in 2nd and 3rd. So far I am very satisfied with the NHP headers and pipes.

My new muffler is out for delivery!!!

How about a 2000 S exhaust system... Will it fit on a 2002 base boxster?

Will I require a mounting kit or any extra hardware?

As mentioned previously, Porsche changed the mounting system on the base car in 2000 to be the same as the S...2.7 and 3.2 are interchangable.
