Had my car in for its first MOT this morning. As I half expected, it failed on emissions.
My car is running a tweaked LS3 with no cats, I didn't build it so I don't have all the information, but as I understand it, it was originally built with a cat exhaust then swapped post IVA for more power.
Has anyone had experience with retro fitting cats into an exhaust? Any alternative suggestions?
Also, this is one for the factory I think, the headlamps failed as they tick up the wrong way. Are the headlamp units switchable for LHD/RHD or do I have the wrong units? If they are wrong, how simple will it be to swap the units to the correct ones?

Thanks for the replies (particularly GT5594).
The car is registered 2012 with an LS3 so there is no getting around the fact that the car needs to pass the full emissions test. The tester was fully aware of the regulations and knew that if the engine was pre '92 then a much less strict measure was due, unfortunately the engine is way past 1992!
My problem is that the engine in its current tune will not pass emissions, I understand from the previous owner that it did pass when fitted with exhausts with cats, and I am picking them up on Saturday in the hope that fitting these will be enough.
I am a little concerned, however, that this will not do the trick as I am currently running something like 5% not 0.7%(?). Backed up by the fact that the back of the car is covered in soot! I do know that the car has been "tuned" post SVA although I'm not sure what was done and I cannot find the garage that was supposed to have done the work (LS Performance or similar near London?). Does anyone know if it is possible to map the Partsworld LS ECU and who can do this otherwise I have a nasty feeling that the previous owner may have been ripped off and "tuning" consisted of upping the fuel pressure (which I can easily verify with a little time in the garage).
