Porsche ceramic exhaust

http://brentwoodrocketscience.com/r2/r2.htm

I acquired a 3.2 liter engine last year for the RSR project which was ulitmately sold as a rolling chassis. After some difficulty trying to sell the 3.2 longblock, it hit me one day...Why not build it and use it. After all, my 72' 911 chassis is pre-emissions so all the stops could be pulled out for a little hotter engine.
So, through word of mouth the 2.7 built almost 2 years (and 3,000 miles) ago is finding a home in a nicely done 914-6.

Nice mention of ceramic exhaust on Porsche.
