Good report Charles. I am 99% sure that the pictures I've seen use stock headers and still use 2.5" OD pipework throughout, so there should be no change in the clearances anywhere at the front of the car. Is it not just the silencer section that is (necessarily) bigger section?
I hope to see it for myself on Sunday though.
Yes that is correct, the header is normal for minimal changeover hassle.
However, a wider silencer requires a slight offset as you will see on sunday otherwise it will interfere with the body and not fit in-line on the two mounts.
The offset is between the cat and silencer and part of the new package.
