The Akrapovic is strictly for track use only and not legal for public road use.
Standard disclaimer due to noise increase I suspect. The optional link pipes i.e. OPF delete are more of an issue I would think.Twinfan said:
It's time to remove the undertrays and put them back on that adds to the overall time. I think around 3hrs is about right if they take their time and don't break anything in the process.
you can do it in a hour with 2 people no issue. I would be pissed with a charge for over 2 hours for very basic spanner work on a new car.the 718 undertray is modular so only a few screws.
I suspect there's also time allowed for the exhaust to cool, there are also quite a few screws to undo and several parts to remove (including the rear diffuser tunnel) to fit the new exhaust. It's not just 3 screws and a single plastic tray.

I hate the word "several " it sounds a lot but it's really not. the words used for effect when it's more than 2 parts lolIt's a one hour job FFS, 2 max if you want a cup of tea 1/2 way though.
Irrespective of what we think, they’ll have got the job card from Porsche which will tell them how long they should book.... so they’ll just charge for that, at their rate.
Not sure there is room for negotiation here.... unless you do want to just do it yourself..... which you can do if you have the tools.
I bet it takes you longer than what they are quoting!
You can also get a quote from somewhere else... JZM is literally down/up the road, off the A41

JCR, for one and I’ve seen people in the states bolt on an OAP with no issues, no CEL. I did wonder if that was because it’s a US spec car but the JCR one won’t be?
I’d there’s no CEL/ECU work would you be tempted?
US GPFs aren't monitored, they can just swap them out. I'm not convinced the JCR option doesn't throw a CEL, but it depends how they've got round the problem. Maybe they just chuck a sensor in anyway and that's enough for the ECU not to have a problem.I’d there’s no CEL/ECU work would you be tempted?
I'm not in the least bit tempted, no.

Hi Dave, I'm not in the least bit tempted, no.
Where are you with an exhaust, did I hear you had one but there was a problem getting it fitted ?
I'm wondering, the standard even with the sports button on is a bit average, I need to do the research everyone else has done, which is best option and how much difference does it make. Not interested in removing filters, so just looking at the silencer swop. It is difficult just watching youtube vids to get an accurate idea of the sound, so any advice would help.
Have you spoken with your OPC for their opinion regarding warranty as that is my main concern.
I did listen to a video of a GT4 / JCR system on Archie Hamilton site which sounded sublime but I guess that was a full system GPF's removed.
Currently just cannot make a decision for every + I can find a - guess its a sign of getting old

I went for fitting attempt #2 this morning actually, but now the small bullet silencers foul the chassis. Last time it was the pipepwork! We're sending my car off to the fabricators in a couple of weeks where they'll get it spot on. Should maybe have done that first time but we didn't know quite how exact a shape the exhaust needs to be. It's a close fit in there! I'll have the car completed in about 3 weeks, so I can probably tell you more then. As of right now, I can tell you that JCR and BCFabs are very expensive options so if you're happy to wait a bit longer my Ninemeister system will be much better priced
I've not spoken to my OPC about the exhaust yet, just my insurers. I don't think talking to an OPC is much use as the crunch will be if you have to make a claim, and then it'll be Porsche's call not theirs. However, under the new car 3 year warranty Porsche need to prove it's the exhaust that caused any fault and as it's only a silencer I reckon it'll be pretty hard to do. I'm not planning on running the extended warranty and will probably look to do some more mods after year 3 e.g. lightweight battery, change of wheels, maybe some engine tuning etc, It'll all depend if an electric Cayman comes along or not. Obviously running the extended warranty with an exhaust mod is a bit of a daft thing to do.
I hope that helps, if only a little bit
