You need Article 7 from this text:
http://www.fiawtcc.com/uploads/regulation/technical-regulations.pdf
But, I think the most important part of the text for you is the following:
"The exit of the exhaust pipe must be situated at the rear of the car, within the perimeter of the car, and be less than 10 cm from this perimeter. The section of the exhaust silencers or of the catalyst itself (perpendicular to the gas flow) must fit into a rectangle the aspect ratio of which must not be greater than 2.5. Furthermore, the perimeter of the section must be convex at any point."
If I understood right what would you like to find out...
I'm an engineer currently making my second graduation (master)Hehe, I'm studying engineering
