Remember not everyone subscribes to the pre-cat failure theory. More problematic is not checking your oil and running spirited with low oil levelI'm new to this board and new to Spyder ownership (2 months). After reading/hearing about the pre cat issues I'm hoping someone will have a link to procedure for replacing and a good parts source. I have average mechanical skills and would like to do this myself. Mine is an 02 with 60K miles. All is fine but want to be pro active. Any help is appreciated.
