Porsche 968 sports exhaust can you get one ?
Discussion
You can purchase them off the shelf from so called Porsche specialists but they often cost way in excess of Porsche main dealer prices. I had a Cat Back stainless steel exhaust manufactured to my own spec by 'Blue Flame Performance' near Skelmersdale J27 M6. They manufacture 'Mongoose' stainless exhausts as well as the exhaust systems for the TVR factory.
www.blueflameperformance.com
The system took a day to make from 304 Stainless steel with my choice of silencer configuration and tailpipe design. The cost was £450 inc vat and fitting (I did provide the CAT flange O-ring - £14 main dealer). Main Dealer - circa £520 including tail pipe.
It sounded fantastic, deep yet sophisticated and not overly loud as well as looking superb.
I say sounded (past tense) because I wrote the car off in a torrential rain storm - ah well I still have the memories of how good it sounded.
Note: do not expect any performance improvement whatsoever as the OE Porsche system has been developed to maximise performance from the Variocam engine. Also DO NOT attempt a de-cat as this will reduce performance as a result of too little back pressure to enable the Variocam system to operate effectively. When researching the market place for an exhaust, I heard of tuners losing 8hp top end and reducing mid range torque when testing cat by-pass pipes on otherwise standard engines. For more info on this matter check out the numerous posts on www.968.net
I hope this helps. There are numerous companies offering systems off the shelf but they are ultimately custom made by an exhaust fabricator. Cut out the middle man and go straight to source is my opinion.

Ps: as though this mail wasn't long enough, if you need more info about other exhaust companies I contacted, drop me a mail.

did the exhaust note take on a deeper tone?, the standard system sounds a bit dry and "thrashy" to me and lacking in burble and bass
anyone got any opinions about the various induction kits/cone filters you can get for 968's?
most claim wild power increases but if they improve the engine note id be interested

Have a look at ninemeister's posts through his profile.
9m is valiantly trying to get more power and better breathing into the 968 engine.
Normal chip, filter and sports exhaust remaps may elicit a small increase in performance and a far better sound, but I gather the 968 doesn't respond that fantastically to mild tweaking. Chuck a K&N in the filter box, or put a cone filter on if there's one available, but I doubt there would be a huge difference in induction noise. Some argue that cone filters draw in hotter air and can be detrimental. On a 968 my take would be to leave it as standard unless I wanted 9m to go to town on it. The engines are not the best thing about them - the handling is.

i know 968 power gains need more involved work, just wondering about engine/exhaust notes
i remember seeing a yellow CS around my area (kingston) which looked and sounded very purposeful
the exhaust system/tail pipe looked alot bigger than normal and was loud enough to draw a fair bit of attention, as ppl say its unlikely it was decatted (a cat is another silencer on the 968?) just wondering what other types of systems there are out there that could make such a difference
sorry if this sounds a bit "muppety" to you lot, as you rightly say the 968 is about handling but that doesnt mean you cant try to improve it if not with power gains then at least a better sound

Yip don't ever assume bunging on a 'cone' type airfilter will give you huge gains.
I recently saw a very nice low miles 968 with a nice expensive cone type filter put on the rolling road and it pushed out the grand sum of under 200bhp!! the normal airbox was not available at the time but a different type of airfilter robbed from another car saw the power rise by 15bhp!
Ps Clubsport- good lad, theres nowt wrong with 16V Golfs

under 200bhp? ouch!
ive still got my corrado 16v outside, started it today and i still reckon it sounds better than the 968 with a more distinct offbeat 4 cylinder growl
it does have a full decatted supersprint system tho which made alot of difference
once fully warmed the 968 sounds ok and has a touch of that classic porsche "dry rasp" from the exhaust but i reckon its stuck in being too smooth for a 4 but not smooth like a 6

There isn't any harm in getting a better sounding exhaust on it (I favour tuneful exhausts myself), but the 968 isn't a car that lends itself to this kind of tuning for some reason. Whilst there are a million systems for 911s, people tend to forget about the 968, 928 etc.
Also, I'd be surprised if it ever sounded fantastic. Louder and more purposeful? Yes. Fantastic? No, it needs more cylinders really...
You may still like to try Manu at Scuderia Systems (see link from PistonFest site) for a Ruf or Tubi system for it, or Haywood and Scott (might be able to google it or someone else will have the number). Plus someone posted another interesting exhaust manufacturing source earlier.
If they can't help, visit renegade hybrids dot com!!! Now that WILL sound fantastic. LOL

I met a guy last year who had a track prepared CS with a TechArt system on it. To quote him it cost a fortune, did nothing for performance, and had an annoying resonance buzz.
I'm sure I recall 9m on here a few months ago saying he was evaluating an aftermarket system for the 968, so might be worth talking to him.

Yip Ive got a similar thing with my 944S2 & 16v Corrado, the Corrado does sound more fruity- not quite got the grunt as the S2 tho
mind you I do have a plan to change that.... I have a spare sports exhaust that I had specially made in 304 Stainless Steel for my 968 Sport quite a few years ago (about 6 years ago I think). I used to run the 968 Sport & Club Sport Register in Porsche Club GB and I had it built to see what difference it would make. In combination with a performace chip it added just under 20 bhp at the wheels (it has a straight through pipe replacing the cat), which I seem to remember proving on the rolling road at the time. It sounded a lot more bassy than the regular exhaust but wasn't boomy on motorways. I seem to remember when we tested standard 968s at the time that none of them developed the 240bhp that Porsche claimed, the best we could find was 231 and mine was around 229bhp at the flywheel. With the modifications applied (superchip, filter & exhaust) it produced around 251bhp at the flywheel, which was noticeable not least for the improvement it provided in lap times around the track.
I still have it up in my loft if you'd like to have it, but I'm not sure if it would fit the Cab or not. I seem to remember that the underside of 968s differed between model years and it depends on how the exhaust goes around the rear suspension.
p.s. I also have a set of AP racing discs and 4-pot calipers for the 968 in a 330x33 size that I'd be prepared to sell. Again they were bespoke and put together for me by AP at the cost of £1500 and covered about 6000 miles before I removed them to sell the car. They come with a new set of Performance Friction carbon metallic pads.
Anyway if anyone is interested contact me on davies_steve@btinternet.com.

Hi
Have just puchased a yellow 968 sport for a bit of fun and it came with a pretty fierce twin-tailed exhaust.
I keep meaning to inspect it to ascertain the make. It was put on in Germany many moons ago, apparently.
All I can tell is it looks fantastic and sounds fantastic. I have no idea if there are any performance changes to the car, not having been in a standard one. I also havent found out if the Kats have been removed/changed.
I will know more when the car gets to a specialist next week for a cambelt/pump/trim repair adventure.
How do you put up pictures , I will put a couple up if anyones interested.
Cheers

Best thing to do is stick 'em up at fotango.com in the public gallery, with a link from here. That way the thread doesn't take an age to download if people are viewing with 56k modems and they are big pics.
Would like to see them, BTW. Twin exhausts sounds interesting on a 968...
Also, as a moderator, may I welcome you to the forum

It has no markings on it, so assume it has been fabricated to order.
It is a normal exhaust, including cats, up to about a foot infront of the rear axle. It then goes into 2, what look like 18" long by 5" round, shiny steel silencers, side by side. One then leads straight through to one end, the other passes round behind the rear bumper and comes out there. It looks like the pipes after they split into 2 branches are about 3 inches in diameter, perhaps more. The endings that you see are a lot wider , of course, but are flanged and welded as part of the exhausts as opposed to just stuck on bits...
Sorry if thats unclear. It does have a wonderful bass sound and pretty rorty.
It doesnt sound like a cheaper, aftermarket exhaust with its higher pitch. Sounds best on changing down gear and accelerating from low down .
Its loud but not TVR loud and should pass the track day noise tests.. I hope.
Overall, I am happy it happened to be on the car and does indeed make the car sound sporty and only adds to the experience of driving the car.
Anybody living near Woking is more than welcome to hear it. Perhaps it can be copied, though requires the obvious modification of the rear bumper.

After a trip up the A1 on a sunny Saturday DoctorD's brakes and exhaust are now sat patiently in my garage.
Hoping to get fitted next week so will update all on the improvement made over the rather tardy standard CS brakes. Will also try to get a picture up of the exhaust although having seen some of Steve's photos yesterday of his 968 Sport with the bits fitted I have no doubt it'll be a vast improvement over standard.
And to top it off what a nice chap (well, whole family actually!), cheers Steve.

Well, a pair of 330mm disks and AP's finest four pots are now fitted to the front of the Yellow Peril and hell what a difference!
Let me put it in perspective, (having compared myself yesterday) these babies are 25mm larger than MO30 and a even 5mm larger than 993TT fronts.
Given 50 miles for the pads to bed in you can really start to appreciate how these things should have all come from the factory - Pedal solid as granite providing tyre squealing braking ability at the slightest depression of right (or left) foot.
Stage two (three, four....) is to fit the exhaust, chip, roll cage, lose all carpets and interior and fit Bilstein suspension... then double check for any additional unnecessary weight that may have missed the first scan.
Hell I sound like Domster! Frightening but fun
