I saw a nice diagram that helps me understand my Boxster, but it's for a 2005 987. I think I may have an exhaust leak on the driver's side that's noticeable when it's cranked up in my garage.
Can anyone help me locate a nice diagram like in the link below that's for a 1999?
Thanks,
From what I can tell, the diagram in this link came from Topspeed.com.
