996 Gundo Hack

Hi Can anyone recommend garages that can perform the Gundo hack modification on my 996 and if you know, how much they charge. I am in the West midlands. Thanks

Adverts appear on EBay for companies that offer this hack. PCW in Hertfordshire charge circa £400 for this and he's booked months in advance.

Thanks yeah seen him. Only two people on ebay offering the service him and Cybox exhausts systems LTD. PCW is quite fair away from me, £400 and fully booked up for ages. Cybox is £295, pretty close and doesn't seem to much of a wait. Here's the advert. https://www.ebay.co.uk/itm/371377348309?hash=item5677d09ed5:g:G~QAAOSw0w9YVPyp Just wondering if anyone on here has used them?

Hi I got mine done by a professional welder in Worcestershire for £140 cash.. I had to remove the boxes and drop them off with him.. it was about 1 week turnaround..I had a 2" pipe fitted.. Great job www.weldis.co.uk ( Ray Scriven number is on the website.. call in the evening as this is side job) Hope this helps Johnny

I'd be interested in this too. Wondered if it sounded any different to the PCW version?

Thanks Johnny, That sounds perfect and close to me.

Funnily enough I emailed turbothomas in Redditch earlier to see if he's doing this or has done this in the past. I'll update if he does

Hi not sure which part of the West Mids you are in but a company in Walsall I have used in the past for fabrication work would be able to do this for you. Give Exhaust Parts UK a call. https://exhaustpartsuk.com/fabrication-page/ cheers, Tony.

This method is often called the Fisker hack in the US it replicates the Porsche sport exhaust system as the additional pipe is in the same places as the factory set up.. Just without the valve to open and close to turn it on and off. I opted for a 2" pipe but I have seen it done with a 1.5" pipe The welding work is superb and this was the first time here had done a 996 exhaust (you can see if you blow up the pic I posted) which is more then I can say when I watched the guy(PCW I think ) do the other short pipe method on Matt Watson's 996 YouTube vid.

If anyone would like to swap gundo hacked Cargraphic ETR silencers for either the same non-gundo hacked, or Topgear mild silencers then let me know.

This is not a complicated job, any good welder will be able to do the work if you supply them some photo detailing where you'd like the pipe placing. What they'll not do is remove the back boxes for you, but if you can take them off it should'nt cost you more than £150. I had my Dansk Sports back boxes Gundo hacked a couple of weeks back, I phoned about a couple of local steel fabrication companies, one didn't want to know, the other told me to pop along for a chat, after a 5 minute conversation and a few photos he knew exactly what I wanted, he ended up doing a great job.

Were your Dansk's standard or super sound? I've got the supers, and cant imagine how loud they'd be with a gundo!

No, not the super sound nor OE replacement but the Dansk offering that sits between the two know as the 'sound version', in standard form these are a little louder than the stock exhaust. I'd image my exhaust is now as loud as the super sound version, but, only when at WOT and above 3500 -4000 RPM.
