Did the ACE Header dyno results exceed expectations?
The ACE A-350 header is not cheap. But, like a lot of things, you get what you pay for. The ACE A-350 header is a top notch product that provides top notch gains as well. In the past, I have used the trusty RevWorks UEL header on my Scion FRS and my Subaru BRZ. This header provided decent power improvements, while also saving weight. After reading all of the hype on the ACE A-350 header, I finally gave in and bought one to test out. As part of the test, I first took a number of dyno pulls with my Subaru BRZ and the RevWorks UEL header. With those power numbers recorded, I could then install the ACE header and get the car re-tuned. Once that was done, I went back to the dyno to get the ACE header dyno results. The improvement in power was pretty shocking, actually. My latest video goes over all of the details and clearly shows where the ACE A-350 made more power over the previous RevWorks UEL setup.
