What a great job Brian ! [8D]
That looks miles better.
The Britemax Polish that I mentioned earlier is a two bottle system.
Bottle 1 is for cutting back grime and polishing up.
Bottle 2 is for a more refined polished finish and it also adds protection.
Another way of protecting it would be to put some Gtechniq C5 crystal armour sealant on it.
If your mate next door is protecting your car anyway you might want to ask him if he has anything in his detailing arsenal that would be suitable [

What you say is absolutely correct. There have been confusing statements in various magazine articles regarding the Gasoline Particulate Filter on the 718, including some saying a single large diameter GPF for the 718 models, and one GPF for each bank of cylinders on 992 models. The 2.0 Macan has a separate GPF located in the engine bay as you correctly say. The following quote from Christophorus magazine issue 388 Page 56, supports your statements.
"Because larger exhaust systems don't fit into the tight engine compartments of the 718 and 911 models, completely new main catalytic converters had to be designed......... The filters are relatively short with large diameters to enable flow into as many channels as possible at the same time."
According to that quote, my new 718 CGTS has a new large diameter 4-way cat incorporating a GPF filter within the same unit. This is what some magazine articles failed to make clear.
At the first opportunity I have of my car up on a ramp I'll take some photos of the underside exhaust system and post them on this thread. I may have to wait until the first interim oil change around 6000 miles when the under-shield is removed to gain a good view of the entire exhaust installation. It's a development I am particularly interested in.
Thank you for the helpful tips Jeff and JMR, regarding further corrosion prevention on the mufflers. I'll follow these up.

While on the topic of GPF's and exhaust emissions, according to the DVLA V5c document my new 718 CGTS PDK is rated at 194 gms/km. This is a substantial increase from my previous 718 CS PDK which had a CO2 rating of only 167 gms/km. Despite having the same engine displacement and, on paper at least, only a modest power and torque increase, the new 718 GTS PDK shows the CO2 emissions rating when tested according to the 2018 WLTP standards.
I shall be very interested in how my new car compares with my previous 718 on both road and track after I have completed the running-in process. At present I have only 494 miles up. Meantime I'm keeping the car away from the salty and gritty roads for now until I have the Xpel PPF and ceramic paint treatment applied. This frustrating wait should come to an end hopefully by the end of next week. I'm itching to get some miles on the clock and realise the full potential of this exciting keen driver's machine on roads that I know well.
I'm keeping my fingers crossed this cold snap of weather we are currently experiencing doesn't develop into a full blown winter, as it has done in the Austrian alps recently.

PS. My grateful thanks to George Woodward for his assistance with updating my forum Avatar. I just couldn't get the new photo uploaded despite several unsuccessful attempts.

Brian,
The considerable increase in the CO2 rating for your new car just demonstrates the difference in emissions when vehicles are tested under more representative driving conditions. I'm sure that the fuel consumption figures will also have taken a tumble too..! However, at least the new particulate filter will mean that the car won't be contributing so much to arguably more dangerous "soot" in the atmosphere.
On the meteorological front I fear that we're going to be in for a very cold blast in the coming weeks; just at the time you say you were hoping to get out on the road []
Happy driving.

It's been an agonising wait of 3 weeks, which has seemed more like 3 months, for my booking to come around for the application of Xpel PPF at Spotless Detaining, Perth.
Callum Foster and his team have once again done a fantastic job on my car. The Xpel film is now on the sills, rear wheel arches, bonnet, and front bumper areas. All that remains now is for my car valeting neighbour Mike, to apply the ceramic paint treatment on the body and wheels this weekend. Then, at long last, my car will be ready for action.
Only one more job to do, the wheel alignment geometry has to be set up prior to the Oulton Park RS track day on March 8th. I'll leave that until next month when hopefully, weather permitting, I'll have over 1000 miles covered by then and the suspension will be properly settled-in.
While in the Perth locality, I registered my car with Porsche Centre Perth for future servicing requirements. In the showroom was a beautiful black Cayman R manual, with carbon bucket seats, priced at a whopping £50,900. These iconic models, especially manual gearbox versions with bucket seats, are still fetching very strong prices at OPC's it seems.

The driver's manuals arrived in the post this week. Porsche Chester had already apologised for their omission at the handover due to printing delays and technical data updating due to the WLTP regulations. By being already familiar with the 718 CS, the delay with the driver's manuals did not cause any problems at all.
I was particularly interested to see what the new manual said about the gasoline particulate filter (GPF) as fitted to my 718 CGTS.
By coincidence, I had been reading an article in the current edition of Autocar concerning diesel particulate filters, and it became clear that if these devices go wrong, they can be very expensive to repair. The purpose of gasoline particulate filters is to trap soot, and like their diesel counterparts, they need purging when soot deposits reach the critical limit of around 45%. Driving style has a profound effect on soot deposits, with short drives, low revs, and cold ambient temperatures all contributing to a rapid build up of soot deposits in the filter matrix.
So it's essential to give your car a good blast of revs on a regular basis to help keep the particulate filter in good shape. For me, this should not present much of a problem as I have a daily driver Abarth 595 Competizione for my shopping trips etc. When the soot particles reach a critical level, the ECU triggers post-combustion fuel injection to increase the exhaust temperature to around 600 degrees centigrade. This action is called active regeneration. However, the downside is the amount of fuel required during this process causes some of the unburnt fuel to end up in the sump causing oil dilution. This eventually gets burned off by the engine but naturally leads to more soot deposits. Great!! More frequent oil changes may become necessary with cars fitted with GPF.
With this in mind, I shall be keeping a very close watch on my 718 CGTS during the coming year for any signs of problems with the GPF. My driving style, and the type of roads I do most of my mileage on, plus my track day activities, should minimise the build up of soot in the GPF. That's what I'm hoping for anyway.
I shall keep this thread updated with any issues arising with the GPF or ECU message warnings. In the driver's manual is a section devoted to the possible message warnings arising from the build up of soot in GPF unit. I have attached a copy of the relevant page for your interest.
Things were far simpler before catalysers and GPF's came along. I just hope the wonderful naturally aspirated engines in the classic cars we all love to enjoy, are not eventually outlawed by the ever-growing environmental demands.

All good info Brian. At least GPF don't need a Urea tank and it's a good reason to drive enthusiastically
Hello Brian
I don't think you will have to worry about any problems with the gpf due to the sort of driving you do, when I worked in the industry when particulate filters were only fitted to diesels we used to get problems particularly with one manufacturer due to insufficient advice to customers from sales people and customers not reading the manuals, the pop to the shops just down the road and school run brigade mostly, I always make sure our diesels get a regular long run/workout to keep them clean.
The page from the manual is interesting the advice used for the diesels anyway to be that the vehicle should have a regular say weekly run at a constant speed 60-70 mph for 15-20 miles to allow the ecu to carry out the regen programme any major variation of throttle would cancel it, it must be a different process on the petrol engines which in any case will make a lot less soot to begin with.
There was a backup process if the light came on and the vehicle could not clean itself called a forced regeneration carried out via laptop in the workshop probably the same as the one a Porsche centre would do where the manual says to get it recovered to a service center, basically it forces it to run high revs and for the catalyst to get even hotter than normal for an extended period after which you have to do an oil and filter change if after that it does not reset or the light returns it's a new cat, there are companies who claim to be able to clean catalysts but it's a bit hit and miss.

Sandy,
Thank you for your interesting and helpful comments above on the GPF topic. Much appreciated.
Yes, I'm hoping that the combined effect of my driving style, using the full rev range, plus my occasional track day activities, will keep the problems of soot deposit accumulations and ECU messages firmly at bay. I really don't want to be troubled with that GPF error message palaver.
I must say, I was particularly concerned when reading the final message listed in the driver's manual. "Park Vehicle Safely" "Stop immediately in a suitable place" "Have the vehicle towed to a qualified specialist workshop".......... Stuff that for a game!
Not what I would want happening when driving in the remote northern Highlands or the Bavarian alps for example.
Daveotto,
That's a far more realistic CO2 figure for the new GPF 718 CS PDK. The previous figure of 167gsm/CO2 for that model now seems wholly unrealistic.

The ceramic paint treatment has now been completed on the bodywork and wheels by my car valeting neighbour. A new ceramic product has been applied this time, Feynlab Ceramic Lite. The process is exactly the same as last time on my 718 CS, with a preparatory paint cleaner applied first, then mechanically polished off. The supplied sponge applicator is used to apply the Feynlab solution by hand, before polishing to a lustrous shine. The finish on the paintwork is absolutely superb with a silky smooth feel.
It's recommended to allow the Feynlab paint treatment to cure for 48 hours before taking the car out on the road. As cold, wintry weather has returned to the north of Scotland so that's no hardship at present. Hopefully, milder weather will soon return and I'll get some miles up to complete the running-in process of around 1,800 miles.
I'm really pleased with the results of my two stage paint treatments. It has been worth the wait.

My plans to rack up some miles on the 718 CGTS have been scuppered this week by the onslaught of wintry weather. The Moray coast has had up to 4" of snow this week with temperatures down to -7c. The car, now gleaming following the ceramic paint treatment, is resting in my garage with the C-Tek charger connected.
Hopefully, I'll get some more miles up soon and have the wheel geometry set-up completed in preparation for Oulton Park on March 8th. I'm very interested to see how the GTS compares with my previous CS only last October on this challenging track. It's the nearest I can get to a back-to-back comparison.

Patience Brian! Even though the weather is not too bad down here, I can't see my GT4 moving out the garage much before the Oulton Park day.

Following an enforced grounding of my 718 CGTS due to a very wintry interlude, plus a most unwelcome attack of the winter flu, I am now back on the road with my new car.
Anxious to get some essential running-in miles up, last weekend I enjoyed an excellent short tour of Aberdeenshire with a few like-minded Porsche owners from the north east of Scotland. Continuing on the same theme, this week I had a day trip to Golspie and Portmahomack on the far north east coast of Scotland. With temperatures of 14c and blue sky sunshine, this was getting more like it!
First impressions of the GTS continue to be encouraging. It is definitely slightly firmer on the suspension than my previous 718 CS, despite having the same chassis and wheel/tyre specification. The engine sounds different also. The exhaust note seems more purposeful and less farty than my 718 CS. Again, both have the Porsche Sports Exhaust. The PCCB continues to impress. The brake pedal feel and "bite" is absolutely superb, and no disc rusting or pads sticking after car washing either.
I now have 1100 miles up, and my next job is to have the wheel alignment geometry set up to my preferred specifications. This will involve maximising the negative camber on the front axle with zero total toe. On the rear axle I'll dial-in 2.0 degrees of negative with 0.08 minutes of toe-in either side to give a total toe of 0.16 minutes. I shall be very interested to see what the factory geo settings say when I have the car checked before adjustment. I'll post both before, and after values on this thread for your interest in due course.
So far so good......
