I believe the Euro model has 286hp. Mine has the measly 250hp. I drove mine during the LA downpour a few weeks ago and it was rather scary as to how easy it was to break traction on the rear tires from a stop! AS for burning rubber I guess I have never had the confidence to try it since the car shudders a little when under load....do your cars do this or is my tranny slipping?....what's your style? Mash the gas or hold the brakes and rev the engine and then let off?
As for the exhaust I like the crossover idea. Even as it is now, I take the car to a parking garage with a hundred riced cars and it sets off every one of em if you blip the throttle....oh what fun
I got mine up to 110mph for a few seconds going uphill at about 4% incline but had to back off because buses don't go 110mph. Perhaps when it has better rubber and track available i'd venture out and see what the top end is.
