EXACTLY You can run dual manifolds, or headers but it would have to be a special dyno set up to accept manifolds and a single exhaust.

Ok...I missed the single part. I have seen pictures of single exhaust being tested on a 901 but to get that done it wouldn’t fit in a car. At that point I don’t know exactly how much that would change power going from the dyno exhaust to what would fit in the chassis.
