Do either of you know what the differences are for the modified exhaust system over the standard offering, which appeared to have caused so many problems at production?

As a matter of interest, and to easily demonstrate the problem with the way the Cosworth is currently tuned as standard, on occasions and when traffic conditions allow, I like to indulge in little oversteery opposite lock moments when exiting roundabouts and sharp corners etc, and the ARP4 won't even break traction, there is so little torque. I guess with the uprated exhaust system it will now do this?
