Where is the best place to buy header and cat back system?

I bought A Dynomax Catback "Super Turbo", Cat Co. (Dir. Fit), Pacesetter header, sealed it all up with Ultra Copper RTV, and Torctite fitted stainless strap clamps.

You can search around and find great deals. I bought some from E-Bay, and other sources through various search engines.
Rough prices I paid were:
Header: 250ish (Still think I should have went ceramic)
Cat: 85ish
Cat Back:109
Clamps: 70
Total $514

I did also get new O2 sensor
M.O.R.E. motor mounts soon after to protect against future engine torquing
