Maybe I don't fully understand the question. Topicstarter is worried that he will not be able to pass the emissions test. Right? I replied that the emissions are no more than before setting the tune. If you know how the test is conducted, what parameters (in figures) should show, then report. Still, as I understand it, he removed the catalyst and installed RRE headers.
The melody is tuned to a lean AFR mix. And it gives a smaller emissions than a stock tune without a catalyst. This will meet the Euro-2 emissions standard.
