exhaust comparison for 98-up accord

'sup everybody. i just got my '98 accord coupe not 2 long ago, and it's time for some performance upgrades. i'm gonna start with the basic 3 performance enhancers first (headers, exhaust, intake) and work my way from there. as far as exhaust...i'm in a little dilema as to which system to go with. greddy puts their name of high quality on everything they put out. i've gotten good feedback on dc sports. skunk 2 kills at the track, and Tanabe...well...tanabe is so damn expensive, i wanna know why. could anyone help me out? also if anyone has seen good results concerning the other 2 basic upgrades, i'll keep them in mind for when i get to them. thanks.
