as the precats tend to get really hot and generate some NOx of their own. Its good in a way because being hot reduces HC, but increases NOx. Removing them will probably lower the NOx and raise the HC - but please - do not quote me on that. Anyone who is anyone here will know that there is really not any good way to determine the results unless you simply do it and test it. Empirical results are the only good results... everthing else is just heresay.
