The eternal question: 996TT aftermarket exhaust

[CraigBruce]

After 3 years driving a 996 C4 Cab with PSE, the sound effects in my 996 Turbo S Cab are seeming muted and I'm considering a new exhaust. As a daily drive I was happy with the volume of the PSE equipped car and didn't have the option of the fancy Off switch - ideally I would look for something with a similar volume level...but which.

Realistic options seem to be:
Tubi Style (2nd Gen) - Tubi offered 'revert if not satisfied' to some a while back
Cargraphic (medium noise version)
Europipe Stage 2 - quiet version

Can anyone advise on real world noise comparison between these and the PSE ? Also which are likely to meet circuit noise limits.

I'D LIKE THE ANSWER TO THIS ALSO!

I'm looking into a custom bypass pipe that does not affect performance or mpg and also was told that some cut the exhausts open, take out all the sound deadening crap and weld back together....

[ROOCK RACER]

Tubi all the way!!!!
HEard a few of the others and they're either too quiet (Like Europipe is but well made) or super loud!

[Jappo]

They all invalidate your OPC Warranty - if that matters. That's why I haven't done it.

[guyvert1]

Don't think it invalidates the whole warranty, just the part you replaced.

Craig
Ref exhausts, I believe the Tubi is the best all round in UK, for fit/finish/sound/price and will deliver 23-25 BHP every time.

You can do a deal direct with Manu at Scuderia on these, or I can get you a TTP system from Das Faderland which is a little more free flowing for a few more ponies/quicker spool etc.

You also need to consider a sports free flow air filter in the std airbox.

How is the car now ??

I have been through this in some detail,

had Tubi... took it off

had design tek titanium.... took it off

now have a Milltek, IMO it sounds how a Porsche should sound and performance is definitely better than the other 2.

I am boosting 0.8 bar consistantly instead of 0.6 occationally 0.7 with the other 2.

check the classifieds!

FYI the DMS exhaust is a Milltek

Do you get any motorway droning with the Milltek?

none whatsoever, very civilased.

it sounds like the oem but louder and with a nice howl as you move up the revs.

I am based in Surrey if any 996TT owners are considering and would like to have a listen.

This could also be of interest.

A must have for the 996TT, it is just too quiet as standard.

I had Cargraphic medium (TUV approved) & was very pleased, but truth be known I purchased "nearly new" at less than the retail £3k plus. Because of the turbos the sound wasn't ever going to be as good as that on the naturally aspirated cars, but you do notice faster spool & extra grunt, overall the extra sound did transform the enjoyment of the car for me. But IMO I don't think any of the packages are worth £3k plus, so my advice is get into a used or cheaper system (providing the cats are good quality otherwise you are into future MOT problems with emissions!!!).

Oh & beware the dreaded 2-3k resonance they all do it but some are unbearable (reputedly Fabspeed etc) & must be avoided!

yest the Tubi noise and drone was unbearable but apparantly that was a problem with the later gen version.

The Milltek is fine and Ihave the 100 Cell cat version and it passed an MOT this week no probs.

I have the Miltek on my GT2, no droning but it pushes the limit at 98db track days.

interesting as the Milltek is meant to be one of the queiter versions, would it have anything to do with the larger K24 turbos on the GT2?

[PHOENIXUK]

Could be induction is making up some of the noise, as the 996TT's that were there'all' with afermarket pipes on were ok with the noise police. I used to have a 996TT with a Billy Boat pipe on, now that was seriously loud.

[CraigBruce]

Thanks to all for the feedback so far, sounds like Milltek is getting more votes than Tubi with Cargraphic an also ran ? Will certainly keep an eye on the PH and fleabay sales of used Milltek's - anyone care to elaborate on whether it's possible to spot a knackered one before it's fitted ?

[pennpromo]

Craig, I have a Milltek, fitted by Ray West at Thruxton, he also did some other work, now I have 509HP on his dyno, the milltek sounds really great, muted at low throttle and revs, no apparent drone, like a banshee at high revs. Nice quality too. You can see the polished boxes just below the rear valance which look quite cool. Recently used it at Castle Combe easily passed the noise at under 97dB.

Hello mate

I have just fitted the DESIGNTEK TITANIUM SPORTS EXHAUST to my 996tt x50. Sound lovely. Not to loud on idle/tick over and pleanty of grunt and spool when at full blat.

I would give a big thumbs up to this system. And it only is 7kg.

All the best and happy hunting.

Make sure you have a listen to the tubi before you dive in.

[wilbo]

stevie f's reply was spot on in my mind. I went out in a 997TT fitted with this system, they have got the power and noise combination just right + it's made out of titanium

I would say this is the system to go for.
