I'm planning on swapping my current exhaust setup with a used Greddy Ti C exhaust hopefully this weekend, and was wondering what size replacement gasket to use? Is it the 60mm, 70mm, 80mm gasket? The site below recommends a 60mm for naturally aspirated motors...so is that what goes on our G's? It may sound like a dumb question, but I'm not really sure
