Stock Manifold problem...
I'm doing this from the bottom of the car (I want to drill them out), however...I just took it into Midas and they said it would cost 600 bucks to drill 'em out.
Sounds like a rip off...but then again, I'm running open headers (which to me can cause even more problems, not just with the police), so I want to put on my new cats as soon as possible.
Any suggestions?
