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 everybody, I'm planning to do the hack to my cans but I'm not sure which one I have. I bought them on ebay but they look like half mki and half mkii (look original not modified). Does someone know what is the modification that I have to do? I did a search and there are many posts talking about but I haven't seen any like mine. -MKII mod (3.6) - from bypass to outlet -MKI mod (3.4) - between the inlet and outlet Here the photo... Thanks in advance, Carles

POST 2Original post

Until about a year or so ago, I was under the impression that all cans with the accordion outlet pipes were 3.6 MK II cans. However, I found out that is not necessarily true. The muffler in your pic has a domed cap on the left side, which normally is found on the 3.4 mufflers, while 3.6 mufflers have a recessed cap. In more technical terms, 3.4 cans have an "outie" belly button and 3.6 cans have an "innie" belly button. So you are correct, your mufflers seem to be a combination of MK I and MK II cans. I have done the MK II mod on both the 3.4 and 3.6 mufflers, and the 3.6 cans sounded much better than the 3.4 mufflers with the MK II mod. I would call a dealer parts department and see if they can tell you which version they are based upon the part number. That may be the only way you can really determine which mos, MK I or MK II you should do to your mufflers. Let us know what you find out. Oh yeah, Welcome to Rennlist and don't forget to post pics of your car soon!

POST 3Original post

Why can't Porsche spend their money on developing one good sounding exhaust instead of 3 moulds on crappy sounding exhausts?

POST 4Original post

The cans are 3.4 no matter what pipe is connected to it. They must be from a TIP (auto) MKI If you do a crosspipe/ J-pipe, make it a BIG ONE and you should be fine. Don't use 3/4" or 1" - use 1 1/2 or so. Good luck and post pics, welcome

POST 5 / ORIGINAL POSTEROriginal post

Thanks everybody. I'll post pictures once I do it.

POST 6Original post

POST 8 / ORIGINAL POSTEROriginal post

POST 9Original post

I prefer the Mk I hack even on 3.6 cans. Sounds great.
