I have the inlet/outlet bypass on mine. I cannot remember the exact size, but I think it is 1.5 inch. It is loud but not as loud as a colleagues 997 3.8 with factory PSE.

Well it sounds good, not as loud as I thought it might be but I was going for the quieter side of sporty.

Good bassy tone on start up and light throttle blips, great sound when you floor it but not too loud.

Just right

A new one from Porsche or Bosal.
Get a new filter from Porsche. K&N will give you MAF problems with its oil.

Get porsche to fit these, cars over 10 years old qualify for half price labour rates.

Just sharing some helpful info, many are not aware of the half price labour.

Likelihood is that the nuts and bolts will all need replacing when swapping old exhaust for new, having the car at porsche just means access to parts on site and a swift turnaround...maybe even a courtesy car.

Why pay Porsche even at half price labour when the job is so simple to do yourself.

Rear lights out, Bumper off, heat shields off, tail pipes off, old silencers off, new (modified)silencers in and everything back on.

Took just 2 hours and requires just basic tools. Phillips and a flat blade screw driver, a torx drive 13 &17 mill spanners

Or a decent Indie who will almost certainly have any parts required, be just as cheap, if not cheaper than OPC & won't tell you your brakes are below the recommended limit etc etc...

Don't want to upset you Roberty , but the Dansk boxes you have got are just a replacement for your OE ones so they will just sound the same as stock, i have the dansk sport which sounds a bit louder than stock which i am happy with, then there is the super sound dansk which i have been told is a bit to loud.
They do the OEM replacement in Standard and Sport. This is the OEM Sport.

They also do a Sport Sound and a Sport Super Sound. Perhaps yours is the Sport Sound which is a physically smaller box, the sport super sound is like the Porsche PSE with a valved bypass.

See here: DANSK Range


Mine is this model:

EXHAUST MUFFLER / SILENCER SPORT OE STYLE. PORSCHE 996
Code: 99622096330S
Replacement Rear sport exhaust set OE style. Polished stainless steel. With TUV/EEC approval.

Made by DANSK

Fits:
Porsche 996 C2 / C4 / C4S 1997-05
Looks like the "EXHAUST MUFFLER / SILENCER SPORT 'SOUND VERSION'. PORSCHE 996" ( Code: 99622096335SSOUND") just has an elaborate Gundo Hack added...

Is that elaborate gundo hack not the same as the 996.1 pse from the factory?

Think so, except not switchable and the factory PSE bypass was 1" (I believe)

I've just fitted the Dansk 'Sports' rear boxes to mine, although they look completely different to those pics, in that they are of completely different design with no folded seams to rust etc, more like a cylinder made from one sheet of SS with two end pieces welded in place.

Sounds deeper & slightly throatier at idle but then slightly louder & richer all the way up through the rev range, without being too loud or droning.

Is that the OEM replacement Sport, the Sport Sound or the Sport Super Sound?

The "gundo hack" are the switches, and you are saying it's not switchable? This version has no TÜV anyway.

Hmm the Sport I think - deeper & throatier than stock but only subtly so - sounds delicious further up the rev range

Simialr to this but slightly different with the concertina flexy sections

Gundo hack is the 'hacking' of the pipework, nothing to do with switches.

The gundo hack is not switchable

Ok guys, thread resurrection.

Anybody had any experience with Cargraphic? My local Indie is recommending them, quoting c£1200 fitted so not a cheap option, he suggested sticking with standard but I'm keen to go with a sportier sound if I'm spending that much money!

Have a week or two to make up my mind now, still no further forward than I was in the beginning!

The OEM PSE for the 996 went through 2 fundamentally different iterations. The early 996 PSE for the 3.4 was just like the pic above - essentially a valved Gundo hack. The later PSE for the 3.6 dispensed with this and routed the exhaust gases through different internal paths within the silencer for loud/quiet modes. Below is a pic of the 2 versions - the later version is the large pic, the earlier the inset.
