IMO I am more interested in how the after fire effect is going to sound. In FM3 none of the after fire pops were loud enough. They sounded about right inside the car, but in the behind the car views, they were drowned out by the exhaust. The visual effect is a nice touch though. Now will the Panoz LMP finally sound like it's trying to shoot you through it's tail pipes or will it still sound like someone stomping on a paper bag?
You're post was nearly band on.
However there is no exhaust noise on FM3, apart from gargling and popping/banging. It's all engine noise.
I hope we at least get exhaust note on FM4 instead of just testing every car with straight pipes. Changeable exhaust notes when upgraded are also up there in my wishes for FM4.
