I got an amazing deal on some nearly new Designtek Supremacy boxes (they have a pre-installed Gundo Hack).

I am happy with the noise performance of the originals, the quiet setting is just that and the open setting gives a nice note when accelerating hard.

Now onto the use; it seems that by default the valves are open, and you cannot switch them off when the engine is off - makes sense since they are operating valves by vacuum.

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 All, Am looking round at options for the back-box on my 996 C2. I have a Top-gear 200cel 63mm X-pipe to fit this winter and trying to decide what back box to use with it. Was thinking about Top-Gear sports boxes. Would love their valved exhaust, but cant justify the price tag (even if there is a group-buy later in the year). Was wondering if this might be the compromise: https://www.ebay.co.uk/itm/PORSCHE-...eel-Valved-Exhaust-Silencers-Set/332724170839 Have searched on the forums and seen Spyder come up, in relation to coffin arms and also for the 83mm plenum. But nobody has mentioned their exhaust systems. Wanted to see if anyone has tried one? As the car is a keeper (assuming nothing major happens), the lifetime warranty on the Top-Gear products doe appeal. Cheers Ben

POST 2Original post

Tempted by this myself so will be interested in any feedback.

POST 3Original post

I've bought one, arrived last week but I haven't fitted it yet, I'll post up when I do

POST 4Original post

Any idea when you are getting it fitted? I'll need to swap mine out before end of September.

POST 5 / ORIGINAL POSTEROriginal post

Hi Effervesce - thats cool. What do you think of the quality of it (realise its purely based on visual inspection). What cats and manifold are you going to use with it? Realise its cheeky to ask, but if you get the opportunity, would love a video/sound-clip (when its fitted). Final thought: This forum is great for linking people.

POST 6Original post

dean that runs Eporsche in woking are behind spyder and their stuff is good. well worth a shot at that price too.

POST 7Original post

Thaks good to know, as my first thought was oh hope its not Dansk quality and more topgear quality. be interested in hearing a soundbyte when fitted. :thumb: :thumb:

POST 8Original post

I bought coffin arms and tuning forks from Dean and they're fine and very good value. I've bought other stuff from him too, good guys to deal with.

POST 9Original post

Just received the exhaust. Looks well made. Fitting next week. Has anyone fitted this one so far, how's it been?

POST 10 / ORIGINAL POSTEROriginal post

Be interested to see how you get on Cvega. Keep us posted. I got an amazing deal on some nearly new Designtek Supremacy boxes (they have a pre-installed Gundo Hack). http://www.designtek.eu/Exhaust-Muf...UPREMACY-DesignTek-for-Porsche-996/prod17391/ I am yet to fit them. However if these dont give me the sound I want (very personal - so cant say till I hear them on my car) - I will try something else and the Spyder ones are on the list.......

POST 12Original post

Looking forward to hearing about the fit and your opinion on performance. I will need to replace mine sometime soon, they can only be bodged for so long, and these are certainly well priced. I am happy with the noise performance of the originals, the quiet setting is just that and the open setting gives a nice note when accelerating hard. Thanks for your feedback. Regards

POST 13Original post

I had PSE fitted to my last 996 by Agnews in Belfast. At the time it cost £1200 fitted! .. and was certainly the very best mod I did. It brought the enjoyment of driving to a new level. I'd like to reclaim this without paying current PSE prices .. I'm very interested in this Spyder system. Please do report back once fitted.

POST 14Original post

So - had it fitted the other day. I know I'm a bit useless but haven't recorded any clips so far. I'll get round to it when i drive the car next. Installation (done by Kev / DW) took a few hours but it was mostly down to how rotten and sad my original exhaust was: Caution - this exhaust does not come with any installation kit - so no brackets to connect to the cats, and no clamp to connect your old exhaust tips. Those were absolutely shot on my car so add that to the cost when you are considering this kit - or use someone like Kev / DW who will just sort them out for you on the day - brilliant. Now onto the use; it seems that by default the valves are open, and you cannot switch them off when the engine is off - makes sense since they are operating valves by vacuum. Doesn't bother me but worth mentioning. Compared to the standard exhaust, even with valves closed it has a lot more bark. When you switch them to ON (valves open) it's quite loud. I love the sound - it reminds me of older 911's at full chat. All in all i think it's worth a punt for the price (I got mine for £600 delivered thanks to an ebay coupon). We'll see how it holds up - it has 1 year warranty compared to others.

POST 15Original post

Have you got the vacuum tank and check valve from the proper Porsche PSE installed? This should hold the vacuum and keep the valves in the closed/quiet position for start.
