My new car

I just bought a black on black 1998 Honda Accord V6 coupe EX! I really like it so I am going to tint the windows and put 18" chrome pcw wheels on it this week.
My future plans are to do some high quality suspension including shocks, springs (maybe coilovers), front upper strut bar, upper rear "sb", and lower rear "sb". I have been looking into the Hayame Coilovers and the Tein coilovers but don't know much about either yet. Do you guys know much about either or an even better setup?
I am having a hell of a time finding headers for this car. I also am interested in a good quality deep sounding exhaust (not loud, raspy, and annoying). Something that sounds like a Cobra Mustang would be great.
Any help would be very appreciated!!
