  1. I've used aftermarket cats before - had no problems. Recommend Maxspeed Motorsports for them - made in Taiwan, but they are very nicely made. I use the racing headers from Maxspeed now on my track 986S. Changing the cats/headers is not a hard DIY - most of the header bolts are easy to get to...not all, but most. $2600 for new cats/headers installed is nuts. California is a little different. http://www.arb.ca.gov/msprog/aftermktcat/aftermktcat.htm
  2. Tim, I'm in the same boat. 98 boxster just failed smog and looks like it might be the cats. However, we have a real problem. As stated by Geoff there are new laws governing what Catalytic Converters can be installed. At this time there are NO aftermarket converters for the BOXSTER that are CARB approved. How can I be so sure?? I manage a performance exhaust/muffler Shop in the Sacramento area. If you were not to far off, like me, you might just want to get it warmed up a little more. I passed on the 15mph and failed the 25mph by 8 points on hydrocarbons. I’m going to change the plugs get it good and warm and give it another shot. If you can find your smog sheet post what you failed on. Colby
  3. New to forms with a few question. I just purchased a 98 Boxster (my first Porsche) and the Check engine light has now come on, code po1539, I took it in to an independent Porsche shop and they diagnosed it as a bad camshaft adjustment solenoid. I replaced the Solenoid and I still have the code. The Car seems to run fine so I am thinking it must be the camshaft position sensor. Any advice would be much appreciated. Also how hard would it be to swap a 3.2 boxster S engine in to my car?
