Two OEM mufflers, which is which?

[rijc99]

Does anyone have access to check part numbers?

I would check the muffler part numbers for:

2000 Boxster
2000 Boxster S

2003 Boxster
2003 Boxster S

Maybe the top picture is for non S Boxsters and the bottom more direct muffler for the S?

I found the following by looking on ebay and some parts sites, these appear to be actual OEM numbers as evidenced by the listing having a photo or even a pic of the part number stamped in the muffler. I have no idea if the years (or even the numbers) are correct, but its clear that there are a lot of different versions of these cans. It seems the different years/non-S/S are not the only factors, but that each exhaust tip style generates its own part number for the whole muffler...

996.111.142.02 (?)
996.111.114.05 (00-02)
996.111.121.07 (-99)
996.111.151.01 (00-02 non S according to the ad)
996.111.152.02
996.111.141.05 (00-03 S)

The Dansk OEM mufflers below are at least separated by non-S and S. Some of these are OEM style and a couple match the OEM part numbers. I'm going to take a guess here that the Dansk "Sport Exhaust, OE style" might be the one we're seeing in JD's pic, freer flowing with tons of insulation, while the standard OEM muffler has the chambers and all of them in OE style look the same outside except the tips. But who knows.

I recall hearing years ago - how some boxster enthusiasts raved about the increase in sound quality after they cut open their oem mufflers and remove all of the insulation. This of course involved re-welding it.

Interesting. I envision that empty muffler being a very loud drone bomb, but I'm not the expert. Seems likely that there are a variety of these mufflers out there, though your pic is the only one I can find with the wadding whereas there are many pics of the chambered ones. Someone must know for sure.

Lucky for me I can TIG weld, so whatever donor muffler I find I have options. Though it would be nice to know what I'm looking for before I go buy one. I'll have to crawl under the box next time I have a chance and read the muffler part number, so I can at least look for the same thing. Evan's homemade PSE, here we come. :-)

I have the Dansk polished Sport "OE" style. It is a 2000 S shell polished with no packing. I don't know if the pipe routing is different but it has a mild higher pitch sound & zero drone.

Research (Jeff) Korda boxster exhaust mod. That might give you some answers.

Thanks for the tip. Unfortunately there is very little information on Korda, regardless of where I search. So far I've managed to find out that he cut open and modded the internals of Boxster mufflers. Beyond that, nada.

Ah well, I'm not in a hurry to mod anything, so I'll take my time and keep researching. When I finally buy a donor muffler to match the one already on my car, I'll have a peek inside.
