Need to know from personal experience what the best racing header between the two is. I have everything else on order, just wanted to know which one has the most gains, which one flows better, reliability and what not. Also, I know that the Comptech header is compatible with any other cat-back exhaust as long as you purchase the adapter for it. Is the TODA header compatible as well. Any one with dyno comarisons or personal experiences would be really appreciated so that I can started. Thanks
