Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

Hi,
I'm looking for a non-boomy silencers for my 996 C4S.
I've tried a Sports silencer and they just droned and sounded like a Vauxhall Nova with loud can on the end.
Are there any decent silencers out there that can be lived with for daily driving but sound great when giving the beans?
Any advice, thoughts most welcome.
Thinking about the TopGear Mild Sports exhaust now...
Cheers
Just had a good nose around the site, looks like some clever stuff going on with their exahausts and the sports cats, i like the look of that Akroprovic trombone but it's for a 997.2.....
Bog standard silencers with the bypass are the best sounding high up and perfect low down, it was developed by Porsche like this or a reason with their PSE boxes.
I've got Milltek boxes on mine and it's not the exhaust noise that has been tiring in the last few weeks and thousand odd miles of using it daily (it's tyre noise on mineJ. It sings high up in the rev range but is really quiet when pootling along and at motorway speeds.
I have the cargraphic quiets on my 997. Sound is good, sharper than stock but no louder, with a nicer noise above 4k rpm. I use mine daily, and there's no drone or CELs.
I put the Top Gear Mild Sports on my 3.4 - I quite liked them as the car was a daily and they didn't attract any attention. On the down side, I missed a bit of the rumble at idle I used to have.
Yup, my standard exhausts are totally goosed. Have changed the manifolds too.
The exhausts I tried were the Topgear loud one's, costing me a fortune in paracetamol
:floor: .
So was looking to swap out with the Topgear mild sport ones... just don't want droning anymore. Have to say Topgear customer service is absolutely spot on.
I like the sound of my TG loud boxes (standard manifolds & CAT's), on the motorway it will drone/boom a bit between 2000-3000rpm in 6th on a light throttle opening (70-80mph), it's not noticeable in any of the other gears. My solution is to just leave it in 5th gear until 78mph then change up, above 80mph in 6th the the pitch changes and no more drone, I haven't noticed a reduction in range. I normally have the radio on which also helps mask it but it is noisy if I have a passenger on a long journey.
Essentially don't slow below 80mph and you'll be fine :bandit:
Hi
I'm interested in this as my exhaust is daft, full stainless. The car came with it! It's great fun on a little drive but gets boring on a run. I did wales to London yesterday and described it as my aeroplane on arrival.
