Effect of DC headers on torque curve?

It's definitely not a Yaris!
I was just looking for any definitive back to back comparative graph between a 4-2-1 and a 4-1 that showed that the 4-2-1 enhances low end torque. Whatever that graph was for, the headers had to have been way longer to make that much difference. On the Yaris, it comes down to a coin toss because no matter what you put on, it's too short to make much of a difference betwen the two designs. One reason I chose the Weapon R is because I think that stainless steel headers look really neato even if you can hardly see them.
