I'm building a SE Spyder with a 356C motor and need to find an option for the exhaust. I've got a Sebring exhaust and headers from SE, which are designed for a VW motor with round flanges. A 356 motor uses rectangular flanges mounted at tapered pipe ends. I've got some old 356 exhausts to source the correct ends from but curves in the header pipes will still need a lot of cutting and bending. Anybody have experience doing this and advice to offer? Thanks.
