These questions refer to a wrx that would already have an up-pipe and full turboback.
1.-First of all, are headers a "reliable" option? Any leaks, gasket problems, etc...
2.-Do they increase or decrease spool up time?
3.-Do they provide power in the higher or lower rpm range?
I know I could get more power for the same money or the same power for less money using different mods, so please don't try to suggest something else. I mearly want to know about headers, not the best "bang for the buck". I'm basically trying to decide wether(sp?) or not to get headers then UTEC or UTEC then headers or if headers are even worth it. But for the purposes of this thread , please comment on the headers portion only, as there are plenty of UTEC threads in which I can obtain the info I need.
Finally the fun question...
4.- MRT headers or Maxim Works headers? Do either have the sub-frame rubbing issue? Which performs better in which areas, high/low rpm range, spool up time, etc. Anyone know of true equal length headers that DON'T include the up-pipe section? I want to be able to get my own up-pipe. Any input would be greatly appreciated! Thanks!
