HRC+slip-on vs. Full exhaust

[450rJam]

How much diff would there be between the 06 hrc header with slip on and a full exhaust system ? Basicaly is the header pipe on the full exhaust that much better than the hrc one ?

from what ive been told the hrc header is a very well built header and Honda did there homework!!!I am just adding a Yosh RS7 slip on!!!!I dont think you will notice gains with aftermarket header..Maybe even a little less performance!I am happy with the HRC kit so mine will be staying!!!!!
