Well I know I'll get blasted for this, but I saw a program a while back where they were discussing just this issue, whether to dump the emmissions stuff. The guy on the show was real informative and gave numerous straight forward reasons why it was better to leave it on. I honestly cant remember any of them, I just recall turning off the program thinking my opinion had changed as I thought that dumping it was a no brainer beforehand. Maybe some more knowledgable experts here can sort of discuss this more specifically.
