Reported cause
Do keep in mind that those are just the outer covers that are split and I doubt are leaking any gases unless the problem is deeper.

Has anyone else got any words of wisdom for me - I can't believe that no one has replaced their exhaust in the last year or so.

After nearly 18 years I am eventually considering replacing the exhaust boxes on my 2004 MY C4S - they only just scraped through the MOT recently and are starting to split at the seams .

I'd be tempted to go for Dansk back boxes on my Boxster when the time comes to replace my original exhaust (modified by Carnewal)
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

After nearly 18 years I am eventually considering replacing the exhaust boxes on my 2004 MY C4S - they only just scraped through the MOT recently and are starting to split at the seams .
I have been looking at the Design 911 DesignTek stainless steel system - does anyone have experience of this, or can anyone suggest a better option (don't need switchable or loud sports noise - just routine replacement to last for another 10 years).
Thanks
Chris
If you need continued longevity and reliability (and not tediously loud) , the original Porsche exhausts are a good bet, if you want to stretch to them... made for the car, still sound fine [

Thanks for the comment pse_SC
Has anyone else got any words of wisdom for me - I can't believe that no one has replaced their exhaust in the last year or so.
Mate of mine had a 996 with the PSE fitted, and his were on the way out.
I'm sure he said he was replacing them with Dansk items, not sure though as he's sold the car since then.

I’ve recently put Milltek boxes on my 996 and I love them. They’re not so loud as to be annoying at low revs or cruising but have enough of a growl for "spirited” driving (or in a tunnel)!
Nobody went anywhere, so I guess not many did
I have a Miltek fitted. It was done for me pre-purchase. I was advised that to replace with the original PSE, the back boxes are so flimsy, stones from the RWD will eat through them in no time at all. In the Indys opinion, Miltek gave the best durability and sound, and, I can agree with the sound. As stated above, at low revs, it's normal. Through the range though, it sounds fantastic, as well as in tunnels. Second to third is a a joy
Do keep in mind that those are just the outer covers that are split and I doubt are leaking any gases unless the problem is deeper.
I would strongly consider repairing them.
Also the stock exhaust is much better than most of the cheap replacements available.
Many cheap aftermarket systems will make the car sound awful.
Aftermarket needs to be in the £1.5k before you start to get something decent.
Thanks for your further comments guys.
I went for a Dansk system eventually (Sound version) and contrary to the description, it is remarkably controlled unless the revs are really increased - fitted by my Indy at an all-in cost of less than £1000.
I'm happy.
I had Top gear silencers fitted 18 months ago and I don't get why they are not recommended more often. When they arrived the quality of stainless welding was really good (I'm a bit finicky about the quality being used to sports bike exhausts like akrapovic) yet the cost was ridiculously low (£450 - 500) admittedly mine are the sports sound flavour which are the loudest and won't be to everyones taste, but i'm used to the exhaust from a 1000cc bike in my left ear so to me it just sounds gorgeous.
