Rattle inside silencers
I have been noticing a very annoying rattle and vibration for a while now. I thought at first it might be the new tips I installed, so I had them welded on and still it persisted. It was rattling at idle, but under half load it also made a strange noise like metal pieces flapping around.
Took the car to the shop today and we put it up on the ramps to start banging around.
Turns out the rear silencers have rust parts inside them (both silencers)- when you hit them with your hand, and also further down, hitting the secondary cats, they make the same noise as at idle.
I think my warranty just ran out too. Might be a good reason to get that Eisenmann race finally?

Man thats a bummer
I'm debating to get a custom made system with secondary CAT delete , prices are coming in at around £550
Also looking to just get the OEM tips cut off and new tips welded on £140
Although the eisenmann system is nice , just cant justify £1400 !
Also been looking a this system which is more resonably priced -

Thankfully I had a full system replacement at year 3 due to the exhaust flap failing. Still, my car has done a lot of very short trips and I suspect that will reduce the lifespan quite a bit.

It looks and sounds a fantastic system Stuart, I suppose it depends if your cars a keeper and affordability obviously, from what you've already done I'd guess it is for the foreseeable sooo go for it, your car deserves no less...

Yes I would love it, but I would also love the LSD, which would provide a lot more value for money in the performance stakes.
I can't justify spending £3000 extra on the car this year, so I'll have to pick and prioritise!
Temped to take the exhaust off and try and shake the rust out, or cut open the silencer and re-pack it.

Well if you've got access to a welder etc, that sounds the only short term option other than buying new boxes Stuart, I would'nt imagine 35is exhausts are littering the breakers yards, especially where you are.stuartinzg wrote:Hi John,john-e89 wrote:It looks and sounds a fantastic system Stuart, I suppose it depends if your cars a keeper and affordability obviously, from what you've already done I'd guess it is for the foreseeable sooo go for it, your car deserves no less...

Is it worth doing a find-a-part search on the interweb as a stop gap?
BTW are you still going to the Watermill meet next month? I'm looking doubtful as having some un-expected surgery on 3rd August, it's got to stay an open internal wound and self heal so it's not looking good, pissed off as I was looking forward to that chat and seeing your mods. Not definate though so fingers crossed.

Are you getting the same sound from the secondary cats? If so you may not have a problem with the silencers at all. Given what my Z4 is doing with 'correct' fueling & given the Thunderclaps like Thor... thread I'd suggest the secondary cats may have got scorched and started to fall apart. Now debris from this has made its way into the back boxes.
So you're car is auto-decatting?.. be happy people pay money for that

Hope you can make it, sorry to hear about the unexpected surgery, bit of a bugger

You are probably right - because the noise is not really that pleasanttechathy wrote:Are you getting the same sound from the secondary cats?

The Eisenmann removes the secondary cats and replaces them with what looks like a resonator.
Doh

Quick update, now I'm in the UK I hunted around and found this chap: www.exhaustmods.co.uk I'm booked in for Friday.
He will take out the secondary cats and cut open my silencers, fix all the issues and put it all back together again.
Gives me a bit more time to sort out another exhaust rather than rushing as MHD Stage 1+FMIC seems a better option (additional cooling from the Evo FMIC) which would provide more tangible benefit for less money, given I am still trying to save for that Caterham

Hey Stuart,
No hope of making it to the watermill, gutted, have a great day and thanks very much for offering me a try of your fettled car, was really looking forward to the differences to stock. Hopefully another time.
Take plenty of pics please.
