Custom Exhaust done- Code P0422


I have a 2000 Vw GTi with the 2.0L. It has 119300 miles on it. I already posted this, but I did not get any replies so I will try again. I got custom exhaust done, they took out the resonator, straight piped it there, and installed magnaflow performance muffler. I have not yet checked the o2 sensors, but I was wondering if Vw are know for throwing codes when modifications like that are made. I also heard that it may take a week for the comp. To realise the modifications and that it will adjust itself. Some feedback would be much appreciated. More details under [u:617cb45387]2000 Vw GTi 2.0 [/u:617cb45387]

Do you
have the same problem?
