I also bought some rubber U-channel from eBay to tidy up the edge of the cut slam panel.
The end result
I had to keep trial fitting the RBC to work out how much of the slam panel needed cutting but once it was all done it looked great.
RBC fitted
Solid-Fab manifold and new gaskets

Getting the old manifold and CAT off was relatively easy but the hardest part was getting the O2 sensors off! I ended up having to buy a Sealey Oxygen sensor removal tool (which you can see in the photo below) because a normal spanner wasn’t up to the job because of the way the sensors are recessed into the CAT.
I also used some penetrating spray to help free the sensors but it still took ages to get them out and even had to give the sensor tool a few whacks with a hammer to shock them loose!
Oxygen sensors finally out
OEM injectors fitted to the Hybrid fuel rail
All fitted!
Now the moment of truth, starting it up to make sure everything was OK. As with a lot of things when working on cars, this didn’t go to plan. The car was idling around 4000RPM and I had a small fuel leak coming from the grub screw on the fuel rail where you can mount a pressure gauge.
Switched everything off and managed to work out that there was a hole on top of RBC which I later realised can be used as an alternative mounting point for the MAP sensor. As the loom wasn’t long enough to reach this port I left the MAP sensor connected to the throttle body and tried using the blanking plug that came with the throttle body.
This worked to a degree but the car was now idling at around 2000RPM and was still sucking air in because it wasn’t a tight fit. I managed to solve the problem by ordering a rubber bung from eBay which worked brilliantly!

Now everything was complete and I had about a week left until my 400 mile round trip to Tdi North to have my car mapped by Paul. As I mentioned earlier I was going to have the timing chain and tensioner replaced if it needed doing so I booked a couple of nights at the local Premier Inn because I knew it would be a long day if they did and I knew I wouldn’t fancy driving home that night.
Left home on the Thursday night and ended up taking 7 hours to get there because of about 3 road closures and diversions, and another road being shut while Police cleared some debris that was scattered across a dual carriage way. To say I was shattered when I got to Premier Inn at 1am was an understatement!
Being up north the night before meant my car was nice and cool the next day ready for the clearances to be adjusted and the guys to crack on with fitting the K100 and getting it mapped. Paul said that I didn’t need the chain and tensioner doing so that saved me some money.
Had a nice chat with a couple of FN owners from the type-r owners forum while I was waiting and keeping an eye on the car.

:WOOT
Paul said the CAT was a bit restrictive but is a massive improvement on OEM which it definitely is as it drives great and I'm really happy with it! I might consider putting the decat pipe on at a later date but maybe not until I have some other mods fitted though. A good excuse to save up for some cams I suppose...
Anyway, big thanks to Paul and the guys, done a great job and was well worth the long drive up there. :salut: :bigthumb:
