Especially in that there are catalytic converters in the .1 and not in the .2 - you might run into trouble here; YMMV.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

I just bought this pair of mufflers on eBay and realized they are off a 987.2 after they shipped (I forgot to check when ordering). I'm wondering if I can still install them on my 987.1 2.7L Cayman . I read a few prior posts mentioning that the "inlet pipes need to be cut and welded": how difficult is this for a shop to do? Or am I better of re-selling these and getting a pair of 987.1 mufflers instead? Thanks in advance!

POST 2Original post

@Cake - AFAIK, you're likely going to want to just resell these on. The 987.2 muffler is not the same as in an 987.1. Especially in that there are catalytic converters in the .1 and not in the .2 - you might run into trouble here; YMMV. (BTW - Where in NY are you? I'm up in Boston.)

POST 3Original post

Damn. I'm in west NY but will be in Boston for work next weekend if you want to buy these!

POST 4Original post

Thanks, @Cake - I personally am all set as I just reinstalled my own stock exhaust back on the car. However, if I find someone who's looking for a 987.2 base exhaust, I'd be happy to steer them your way. FWIW, what you have there came from a 987.2 base (2.9L) Boxster as the tip in the picture is the base version. The "S" 3.4L has the double-tip.

POST 6Original post

I did some digging and found something interesting According to the parts catalogue, the 987.2 exhaust mufflers will also fit 987.1 if the 987.2 has the "non-switchable sports exhaust ": Left muffler 987-113-511-31 2007-2012 Porsche Muffler & Pipe 987-113-511-31 | Sunset Porsche Parts Right muffler 987-113-512-31 2007-2012 Porsche Muffler & Pipe 987-113-512-31 | Sunset Porsche Parts However, if the 987.2 does not have the sports exhaust, the exhaust mufflers will not fit 987.1: Left muffler 987-113-117-BX 2009-2012 Porsche Muffler & Pipe 987-113-117-BX | Sunset Porsche Parts Right muffler 987-113-118-BX 2009-2012 Porsche Muffler & Pipe 987-113-118-BX | Sunset Porsche Parts
