HI ALL

Well i finally got arround to fitting my FLYEN dump pipe, the bellmouth one. I have new gasket on the turbo to dump, but old ones on the cat.

Now for two days it was fine, but now, when you start it, it almost sounds like there is an exhaust leak somwhere, but inside the pipe, does it when warm too.

I have gone through all the bolts, all nice and tight, cheacked for leaks, can't feel anything, anywere. turbo, cat, manifold, all good.

The car still pulls like it did, no loss of power or anything.

You can't seam to hear it directy outside but more inside, like inside the pipe. I am thinking that now that the O2 sensor is more in the flow of the turbo, maybe that is making the sound.

I am going to get new gaskets for the cat, and put them in, just to make sure. But has anyone else had a simmilar problem to this?

ANYONE?

nope no high temp sealer between the dump and the turbo, no need, i got a genuine copper gasket, and was told not to use any, nobody i know has, and it is definatly not leaking from there, tripple checked now.

I got new gaskets for the cat, as they are the ones i have not changed, so i will replace these tommorrow night and see where from there.

It is like a leaking noise, but it is inside the pipe. BUT i do not notice any performance loss at all.

ANy other ideas?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
