Frankp2112 Posted May 25, 2020 Report Share Posted May 25, 2020 Hi, I had to get the car through its MOT a few months ago and it needed a new rear box. I bought a cheap rear box of e bay I didn't have a lot of cash and needed one quickly. I now want to replace this rear box as its sounds very loud and drones badly on the motorway. Can anyone give a recommendation of a rear box that sounds close to stock without splurging for genuine Porsche parts. Thanks. Frank Link to comment Share on other sites More sharing options...
Southy Posted May 25, 2020 Report Share Posted May 25, 2020 Hi Frank, If something happened the rear silencer on mine, I'd try and find a secondhand Porsche part on ebay, while it is off the car you could have a number of 'mods' done too it or just have it installed. Five years ago I had the 'by-pass' mod done to mine and it has been awesome ever since. Link to comment Share on other sites More sharing options...
edc Posted May 25, 2020 Report Share Posted May 25, 2020 Look at the Dansk online catalogue. They do a plain OE style replacement. They use the same shape for their Sound and Supersound boxes too. Link to comment Share on other sites More sharing options...
bally4563 Posted May 26, 2020 Report Share Posted May 26, 2020 Some on here have installed motorbike baffles, that quiets it down and stops the drone, do a search on here. Link to comment Share on other sites More sharing options...

John2000 Posted May 26, 2020 Report Share Posted May 26, 2020 @the baron good choice, I got Lee to put one on mine and I love it, no drone not that I've driven it a lot. I'm keeping my old box until after an mot I'm sure it will pass but just incase Link to comment Share on other sites More sharing options...

Madlil Posted May 27, 2020 Report Share Posted May 27, 2020 I had the Dansk sausage type fitted to mine. Think it cost around £800. I was fairly disappointed with it. With hindsight I wish I had bought a standard back box off eBay and had a bypass done. Link to comment Share on other sites More sharing options...
coopers Posted June 14, 2020 Report Share Posted June 14, 2020 I put a Dansk Supersound on mine, no drone at any revs. I kept the original box too just in case, it just takes up space in the garage now.. Link to comment Share on other sites More sharing options...
Berni29 Posted June 14, 2020 Report Share Posted June 14, 2020 Hi I second getting a standard box, but the problem is that they are getting old now and finding one that has its seams fully intact and not too rusted is getting harder.

the baron Posted June 14, 2020 Report Share Posted June 14, 2020 Ive ended up getting a really good standard exhaust from a much later car and converting it to fit the 2.5 as I was worried about cabin boom, although most who have fitted a Dansk are happy there are some reports of cabin boom.

Darren Sapsford Posted June 14, 2020 Report Share Posted June 14, 2020 Luckily got a 3.2 backbox in great condition for £100 and fitted it to my 2.5. Link to comment Share on other sites More sharing options...
