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.

POST 1 / ORIGINAL POSTEROriginal post

Hi Folks, Having exhausted (sorry) other avenues I figured I'd tap into the breadth of knowledge on rennlist and see if someone could help me out with a question regarding the interchangeability of 996 mufflers. My '99 c-2 6-speed is in need of a new passenger side muffler as it has a bad rattle when running cold (spent baffle?). Anyway, I've noticed there's a lot of stock 996 mufflers in seemingly good condition going for short money on e-bay as a result of people upgrading to performance systems but have yet to get a conclusive answer on whether or not a later year 996 muffler will fit my '99 without any significant modifications. The part numbers are different between the '99 and 2000 and the local Porsche service shops can't give me a definitive answer without seeing the parts...any help would be greatly appreciated. Thanks!

POST 2Original post

They all fit. Depending on the year, at worse, you have to do it transfer the mounting bracket from your current muffler to the new one. I bolted on 2003 C4S mufflers on my 99 just a few months ago. 30 minute job.

POST 3Original post

If it's the cans you need you are welcome to mine (free)....just pay for shipping. I held onto mine after putting on PSE in case I needed to revert back but I never see that happening. Not sure what shipping would be though.

POST 4Original post

Ship FedEx ground. It's less than $30 for the mufflers and is faster than UPS despite being half the price... You can definitely put later model mufflers on an earlier 996, but I would not put a 99 muffler on the later VarioCam Plus (02-05). I know for sure that you can't do that with the PSE, so maybe the stock mufflers are the same situation.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the great info everyone...it's much appreciated. LVDell, that's a most generous offer and if you feel that your old "cans" (I'm guessing that's the actual muffler, not the cat or headers) still have some good life left in 'em I'd love to take you up on your offer...drop me a line at [email removed] or [phone removed] and we can figure out the details. Many Thanks, Alex

POST 6Original post

Sure thing Alex. You are welcome to them. I'll email you later. Cheers, Dell

POST 7 / ORIGINAL POSTEROriginal post

Sounds great...thanks again.

POST 8Original post

Dell - Very generous of you! BTW, I think your current PSE's are getting worn out, so you should install some new ones. When you do, I'll be happy to take the "old" PSE's off your hands!

POST 9Original post

Oh Tim.......you are such the kidder this weekend! What did we say about drinking before noon? Anyway, you are welcome to my PSE since I have no use for it anymore. Send me certified funds for $2000 and it is yours.

POST 10Original post

Box 'em up and ship 'em, 'cuz "the check's in the mail!"

POST 11Original post

Sure thing Tim. As soon as the check clears I'll send you the tracking number
