Headers or no?
Need to know whether to purchase the set of headers to my 04 rx8. I will be purchasing both the complete exhaust system from turbo XS and may throw in the new headers from them as well since am getting a good deal on them brand new. 
Having just installed a complete TXS header/midpipe/cat-back system for a customer, I can tell you that I had to modify the passenger side motor mount arm as the AIR pump tube on the header interfered with the aluminum mount arm. Whether or not this was a design flaw or a one-time issue, I do not know.

Yeah it was a pain in *** and not really worth it in the end. His car is stupid loud and the power increase was negligibly.

seriously though, headers will NOT give you too much gain on the power side. it will give u a different sound though. butt dyno will tell you your car has a 50+ hp increase.
Only real good header came from Knight Sports, but even with that (They separated it all ports, not merger like most designs) still only get ya another 3-5 ps over the rest of the market AND it cost you an arm and leg.
say, a RB header + mid/test pipe + race exhaust give u no more than 15 hp on a good day (really good one), so u might wanna think if the cost is worth it. if u just wanna a different sound, an exhaust (cat back) is usually enough.
for best NA power, u need to clean up the cast marks(or do a very mild SP) on the engine + tuning, it helps more than getting a good header+pipe+cat back. it will cost u even more, but better in the long run.
