Hello,
Yes I haven't posted for a long time. Very hard for me when I dont read a word of polish to navigate the site.
I have done a few things since I last posted. Here is some copy and paste!
R32 Steering wheel
Seals + Rear Brakes On + Spare Wheel completed
Rear brakes fitted and some maintenance work done on the car. I requested that all the seals on the car to be replaced to sort out the weeping problems.
- EGR seal replaced so boost leak sorted there. Also new Silicone hose that fits better has been fitted
- SFS Turbo Fixing. The seal was not the correct size. This was mainly due to it being an early version of the fixing so the groove for the seal was not deep enough. The result of this was boost leak from the turbo that just got worse over time. Seal was replaced with a better suited one which looks to have resolved this leak.
- FMIC fixing - all seals replaced so weeping at the FMIC connections has been resolved.
Net results is that the car feels quite responsive. Not sure if any performance has been gained as I haven't pushed it but definitely runs better now.
I had the rear brakes fitted albeit without the dust guards as they didn't come in time. Still bedding them in so will give full review once its 100%.
I had time today to cleanup the spare wheel (new wheel placed on car and the spare is the damaged wheel I am getting refurbed hence the cleaning). I de-tarred, clayed and polished with Autoglym SRP. Took be around 30 minutes but it was well worth it! SRP works really well on alloys and it proved it today by getting rid of staining that claying couldn't shift.
This is now ready to be put in the boot. Going to use bubble wrap until I carpet the wheel well.

Done a lot of driving and running around this weekend so this has put me in a good position to give a “small” review of the new exhaust and turbo outlet pipe.
Scope of the upgrade
I went for a full 3" Exhaust System for the following reasons.
1) Remove the restriction of the Miltek DP. The miltek DP is very good however the outlet of the downpipe is still stock and only goes to 2.5" once past the metal flexi part. This is fine for standard 150PDs and Hybrids however in the quest for more power going bigger is the only way. This also will set me up nicely for if and when I upgrade turbo.
2) Lower Exhaust Gas Temperatures! In the quest for more power its essential to keep the temps in check and with the older exhaust setup it was always in the back of my mind. If I want to do a long trip and track the car on the ring then I want lower EGTs for sure. 3" DP should flow more and thus reduce EGTs. Hopefully turbo will live longer too.
3) Lower noise. Ever since I got the new tip and the 3" piping to center silencer the exhaust was much louder than I liked. I some occasions it was nice to hear the wastegate chatter and the roar when accelerating. Other times I thought it was just too loud and not what the car was about. Knowing that 3" would increase noise I opted for 2 high flow silencers instead of one.
4) See if there are any performance improvements. the 17/22 Hybrids produce amazing results for the size of turbo they are. Some people say 2.5" is more than enough and even fewer say 3" DP improves anything at all.
Sound
When listening to the car on idle the exhaust note is now virtually non existing compared to before. The sound before was very hissy however now the hiss has gone. There is a burble especially now I added some miles and the car warms up but not a massive one. Inside the cabin however the engine note is now a lot lower but louder and it growls nicely when bliping the throttle. When driving normally there is a low gentle burble and definitely a lot lower noise than before. Changing gear there is not hint of a pigeon noise from the back either.
The exhaust really starts to open up at 3.5k. You get a lovely throaty sound but without the same high decibel roar I got before. It certainly makes the car feel grown up and expensive now.
Power
Squeezing the throttle you get power delivery that is now much more immediate. I would love the see the graph because it definitely feels like there is more power lower down. Definitely smoother power delivery and knowing that I said this many times I just can’t believe that there can be so much improvement from freeing up the exhaust. The power delivery was silky smooth before but now there is more torque availability lower down and it doesn't seem to tail off! The Miltek DP and centre silencer must have been more restrictive than I first thought. I am trying NOT to sound too enthusiastic about the difference as I am well aware that many of my previous performance mods made things more powerful and smoother. However I am beginning to wonder whether now I am at the limit of how smooth the power delivery can be with this turbo…seems too good to be true.
Past 3.5k that’s when things really begin to get interesting. It feels very much like a petrol in the sense that the power and sense of speed keep building as the revs climb. At 4K there still seems to be plenty of puff and the engine doesn’t sound as strained as before.
Playtime
As I stated before I had a little play with a new Porsche Carrera S within the speed limit of course (believe they are now 3.8ltr units instead of 3.6ltr and pushing an impressive 355bhp). I think the chap was a little shocked at what he found when he tried to stick on my bum when I first started to test the exhaust. Definitely felt confident in accelerating with the turbo outlet sorted and the new exhaust. I made a good account for myself and I think the fact he could over take me must have annoyed him no end.
Pros
+ Droning noise gone at 70mph
+ Great torque delivered more smoothly
+ Nice and quiet when driving normally.
+ Sounds grown up now and suits the car better
+ Definitely more performance. Might not be bhp but its added something!
Cons
- Expensive
- Got an annoying rattle because its so big. Can be sorted though
- Bang for buck may be lower in the grand scheme of things

Took the car down to good ole AmD today for service. Car has covered just over 40k miles which isnt bad for a 6 year old car. Brilliant service from AmD as always, gave the car a good checking over as part of the service.
+ VAGCOM adaption reset done. Car was sluggish as I been taking it easy for several months so ECU adapted down a fair bit. Now so she is now back to her sprightly self.
+ New OSRAM nightbreaker v2 main beam lights have been installed. Definitely brighter when flashing people but need to go on a country lane with no lights to see if they really do the business
+ New Fabia rear wiper blade installed.
+ New Left hand Drive Dual Mirror installed. Really does take some getting used to when driving as I never had one of the left side on any car i have driven regularly. It works really well on motorway and on busy 3 lane roads.
Toy T1-Rs now all running 32PSI. These are really starting to scrub in now. Done about 100 miles in them and they really are night and day difference to falken452s. Falken 452s are a good tyre however the Toyos are much better suited for heavy diesel lump and the torque that comes with it.
The Mrs was complaining how I dont look after her car like mine. Also I hadn't detailed the car since the cement fiasco so last week I done a full detail on the car. I should have really done a write up but thing I am getting a tad lazy recently with detail write-ups. Got to start doing them again. Anyway This week I re-waxed her car, went mental on the inside with the interior protectant and dressings. She is a happy bunny now.

Ported Cylinder Head has been sent back to AmD. Took a trip to AmD today to get a good look at it. Nice to seem some Automotive Diesel **** every now and again.

AmD RR 20-02-2011
A few pictures from the anual AmD RR day in February. Will update this post if I get any more pictures.
We couldn't breathe over there... And earplugs was used as a noseplugs. 
Your car is impressive, equipment as well. Before I bought mine I have read a bit of Seat Leon and found out that it wasn't that popular in the UK as Golf IV was - great to hear that the guy who wrote it was a dumass 
I have studied Stan's report from Dyno Day, looks like you have army of leon lovers in the UK
