I'm hoping you 356 guys may be able to help on this one. I put a '67 912 in a '73 VW Ghia convertible. I've owned a '63 sunroof and a '57 Speedster (key word-owned

). I'm looking for a single exit exhaust system like they make for VWs but larger diameter tubes that I can use for this application and I remember that I had used a system like this on my other Porsches years ago. The engine came with a Bursch exhaust, but it didn't fit behind the Ghia so we fabricated a VW performance header for temporary use. Any ideas would be greatly appreciated!
