sorry I'm late guys. saw one on a circle track modified w/straight six for sale a while back on ebay. kind of looks like this: comes off head up direction like a fenderwell header, then pipes twist as it runs behind head above bellhousing. then in a direction somewhat down with the collector. looks racy as all hell,and must be as loud too as collector points to the sidewalk(or grandstand in the situation of the race car).
