this is back before they even had thought of making a 3" exhaust. The exhaust actually starts at 2.5 and expands to 3" at the X pipe. The mufflers and tips were custom. So don't compare it to what they have now.
Honestly I been given some thought to go full 3" now and see if I gain anymore HP on dyno. I may post a sound clip of it now. I added another pair of resonators to X-Pipe to kind of quiet it down.
