I've read a lot of posts regarding fumes inside cabin and it appears that two changes can help: 1) Headers and, 2) EFI system to help burn fuel more efficiently. I do smell like exhaust & gas when I get out of cabin so I know it's running very rich. OK my questions for you professionals are this: 1) what is the best set of headers to buy & should one buy the whole pipe and muffler package? seems kind of expensive, can a local guy do it cheaper? and 2) Whats the best EFI system to buy? Thanks for all your help guys - JFK
