Thats what I thought too Bob, that Geoghegan ran an 8-1 exhaust on that car that exited in a nice chrome mage-phone just beneath the front of the door on the passenger side. Geoghegan also ran a full length exhaust that exited out the rear just briefly too. Both systems were quite different to that pictured above. When Coppins raced the car in the '67 ATCC he still had the short chrome pipe.
John Riley commented on the engine note also on this car in an interview. He also said it was a lovely sounding car.
