BigRich Posted July 27, 2023 Report Share Posted July 27, 2023 Hi , New here and just wondering if I am going to regret buying a £200 rear exhaust (twin exit back box exhaust) or do I just take the plunge and buy the OEM silencer from design911 or heritage parts? Is the cheaper twin exit exhaust going to be very loud, any help appreciated. Thanks https://www.ebay.co.uk/itm/354598705049?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338990945&toolid=10001&customid=eb%3Ag%3Avms%3Aeb%3Ap%3A354598705049%3BCjwKCAjwq4imBhBQEiwA9Nx1BqBDTlTAl86JlsMQFkk52szHHabzjwrhyUMt9jRQ9DodPC-Mlry8hRoCjhAQAvD_BwE&_trkparms=ispr%3D1&amdata=enc%3A1Lb_8-uShSCuaTzOe5d7t7g35&gclid=CjwKCAjwq4imBhBQEiwA9Nx1BqBDTlTAl86JlsMQFkk52szHHabzjwrhyUMt9jRQ9DodPC-Mlry8hRoCjhAQAvD_BwE https://www.design911.co.uk/p/exhaust-muffler---silencer-sport-oe-style--sound-version--porsche-986-boxster/ Quote Link to comment Share on other sites More sharing options...
iborguk Posted July 27, 2023 Report Share Posted July 27, 2023 Hi and welcome. A lot of folks talk about drone with those cheap Bay of E exhausts at certain rev ranges. 1 Quote Link to comment Share on other sites More sharing options...
brillomaster Posted July 27, 2023 Report Share Posted July 27, 2023 it really depends how you use the car. the cheap £200 toyosport ones sounds terrible when you start the car up. it sounds terrible between 2000rpm and 3000rpm and its droning. but then above 4000rpm it sounds heavenly, especially with the roof down. proper naughty rasp when you blip the throttle for a downshift too. so... for a daily driver, that ever does any cruising, then no. but if its a weekend car or a track day car more interesting in chasing the redline, then yes definitely. the toyosport exhaust is also a lot lighter than the standard exhaust (cos there isnt much to it) - that and the spare wheel out the front probably saves 30kgs if thats of importance to you. 1 Quote Link to comment Share on other sites More sharing options...
brillomaster Posted July 27, 2023 Report Share Posted July 27, 2023 though, that said, i did once take the missus away for the weekend, in a 986 with a cheap exhaust on - it was tolerable on the motorway, just have to keep the revs over 3000rpm. and yes, the cheap exhaust is a decent chunk louder than standard. but again, suitability depends on how you use the car. 1 Quote Link to comment Share on other sites More sharing options...
BigRich Posted July 27, 2023 Author Report Share Posted July 27, 2023 Thanks for getting back to me guys, it doesn't get used loads but sounds like its going to be a bit of a drone. Quote Link to comment Share on other sites More sharing options...
½cwt Posted July 27, 2023 Report Share Posted July 27, 2023 (edited) The closest you will get to OE without spending all the money for a Porsche one is a Dansk exhaust, best price usually seems to be from, Tech 9 - Porsche Specialist Liverpool, Cheshire, North West (tech-9.co.uk) No affiliation, not even as a customer.

McDonald Posted July 27, 2023 Report Share Posted July 27, 2023 I had a full Dansk system fitted last week. It's louder than the original but actually its a good sound & no drone. 1 Quote Link to comment Share on other sites More sharing options...
deanmr2 Posted July 27, 2023 Report Share Posted July 27, 2023 Does anyone know if Ghert at Carnewal can modify the Dansk exhaust back box like he does with the standard back boxes ? I have heard a couple of Boxsters with the Carnewal mod and I thought they sounded brilliant Quote Link to comment Share on other sites More sharing options...

Everywhen Posted July 27, 2023 Report Share Posted July 27, 2023 I recently fitted a Toyosport to my 986. I put a pair of Drone killers in it and it’s fine. Still makes a decent noise and I detected no difference in performance. At a recent Porsche 75th birthday BBQ I met another 986 owner who Also fitted a Toyosport and had had no complaints. 1 Quote Link to comment Share on other sites More sharing options...
DaveyP Posted July 29, 2023 Report Share Posted July 29, 2023 (edited) Another voice of agreement with previous replies. I've got the eBay box. Was fitted by a previous owner. It does sound great when opened up, but drones like hell on a cruise. The sound that annoys me most is a kind of tinny rasp it makes around town. Reminds me of when we were kids and some dudes would put huge back boxes on Vauxhall Novas. They always sounded a wee bit like the engine was struggling to fill the exhaust, if you know what I mean? It's one of the things that's on my long to do list. I fancy a full Dansk system, but it's way down the priority list as it's not actually broken/rattling!

TV8 Posted July 29, 2023 Report Share Posted July 29, 2023 If I ever sell my 996, then the modifications will start on the 986. Carnwell is an option and I find myself being drawn to this item.

You probably know already but spyder operate out of the la rose site in Kemsing. If I remember correctly you aren’t that far away so you could probably go down there and have a look and a chat to them. Quote Link to comment Share on other sites More sharing options...

Well remembered that man! I called in this week and discussed this (£250+ vat fitting plus and and brackets and bolts required) and a couple of things.

RedBarediver Posted July 30, 2023 Report Share Posted July 30, 2023 I drove with an eBay special DroneMeister for about two years. My original exhaust was finished and I couldn't afford a new OEM or Dansk exhaust. I lived with the drone (from about 2,500 to 3,000 rpm) but can't say I enjoyed the experience. Anything above 3,000 and above it's fine. It sounds absolutely bloody fantastic above 5,000 and you just want to give it more. the more you push it the louder it howls. Just fabulous. It also blows out quite a bit of a silvery dust in the beginning (presumably the sound dampening inside the exhaust coming loose) but after about 200 - 250 miles it seems to settle down. I tried the Dronekiller baffles but hated it. The whole car sounded like an asthmatic moped. it was so bad I drove straight back home during the test drive and took it out there and then. never put it back and just drove with the drone. You learn to drive around the rev range where it will drone too badly. On the motorway because I have a 5 gear 2.5 it was fine (if a little loud) because I kept it at 3,000 rpm. In a 6 speed it may not be so easy as I think you're going to cruise right around the rev range where it is at its worst. It's liveable while you save up for a nicer exhaust, or until you can find a decent second hand one. After two years I got hold of a second hand OEM exhaust (from Paul Lewis) and swopped that out. One of the guys on here took the dronebox off my hands and fitted it to his 2.7. Far as I know he still has it on. Quote Link to comment Share on other sites More sharing options...
Nitro V8 Posted July 30, 2023 Report Share Posted July 30, 2023 I’ve got the Topgear back box on mine and like others above it sounds great when going for it but does drone on a cruise. I think they are all pretty much the same of that type of design. It does look good with the meshed plates under the boxes and seems well made. I bought it cheap and was dissuaded from fitting it originally by Lee at Cotswold as he said it would drone. However my oem back box seems split so had Cotswold put it on whilst for the interim.

Everywhen Posted July 30, 2023 Report Share Posted July 30, 2023 Any drone is sorted with the eBay Drone Killers. £8 is all they are so if you don’t like them its hardly an extravagant waste of money. I’ve not noticed any detriment is performance with them fitted and they are easily removable if you want the full on sound. Quote Link to comment Share on other sites More sharing options...
Tycho Posted August 8, 2023 Report Share Posted August 8, 2023 After 6 months Mrs. T has had enough of the drone from the “Chinese” exhaust, so I am going to try drone killers. There are two sizes, approx. 8 or 14cm long in the 48mm diameter listed on eBay. I realise this will not be a perfect solution, what size has worked best?

the baron Posted August 8, 2023 Report Share Posted August 8, 2023 Drone is a killer, it will only happen at certain speeds, usually motorway cruising speeds and it becomes tiring. Not had it on the Boxster as I have stuck with OEM. I did have it on the 996 when I first bought it, changed to a Dansk exhaust within the first week, just couldn’t live with it.

It seems to be good quality and above 3k rpm it sounds awesome but 2.2-2.7k rpm it does drones a bit. Being valved when you shut the valves the drone is much reduced but still there a little. Didn’t want to play around with drone killers so going back to stock and will resell exhaust to raise funds for a second air con condenser and also thinking about a hardtop. Exhaust will be up for sale from Thursday if you’re interested in? Quote Link to comment Share on other sites More sharing options...

Speaking with Carnwell, it appears that there are lots of options and they want to work on what I have rather than exchange? Quote Link to comment Share on other sites More sharing options...

I just couldn’t bring myself to spend over 25% of what I paid for the car on an exhaust. Quote Link to comment Share on other sites More sharing options...
