The exhaust inside the boot is comprised of two virtually weightless carbon fiber silencers. I wanted to have the maximum amount of space available at the bottom of the car for a diffusor. The car will still get a flat undertray and deep sideskirts and front spoiler to achieve a low pressure zone under the car. I prefer achieving downforce like that rather than with a big, high drag boot spoiler.
As an added benefit, the exhaust pumps air into a low pressure zone, thus minimally reducing drag.
Unfortunately when the exhaust was made, I had a 733i engine mount rubber with a custom arm on the exhaust side. I have now changed back to the M20 arm and nylon engine mounts. This has shifted the engine and that is why the exhausts are no longer in the center of the holes.
