Well, since I started the thread, I probably should speak up, too.

My reading of the rule is that the "body", as per the Glossary, is above the plane of the floor. As such, an exhaust dump under the body, does not conform. I'm reading it to say...it must be directed UPward, above the plane of the floor, to meet the wording. Yeh, I know...the pipe configuration would be very strange!!!

I'm perfectly happy to have mine dump under, as I said I have done in the previous three cars. But I don't think the wording is exactly what the rulesmakers had in mind.

Good racing.
