Question ... why is the race GT going with side pipes..
If your question is to why does the car exhaust just ahead of the driver rear wheel(s??) as depicted in Dave's picture #5 of post 1, my guess would be 1) packaging convenience to a) reduce tubing pumping losses associated with ducts and b) reduce engine bay thermal loads due to radiation/convection and 2) no compromises in body aerodynamics by side exiting of exhaust vs aft car exit.
Man Dave, Thanks.I am soooooo Jazzzed!
Not sure if race car will be there but there will be a presence at Goodwood.
When/where are those going on sale, Dave!?!?!
And last thing, parting gift from the weekend:
