Default problems searching stuff (advice!)

i have a 2004 subaru wrx, and im having trouble searching what type of headers to get my car. right now my dp, to axel back is a 4inch tapered to a 3inch straight back. sti tmic, walbro 255, spt cai and i have a vf43 i havent installed yet because i dont have the proper fuel injectors. and also have tgv deletes, im waiting to do it all at the same time. But i want to do my header before turbo/injectors. i see some people have problems with oil pans in the way or just buying the wrong header all together. what i want to know is should my headers be 2.5'' or 3''? =( sorry if i really seem like a dumbass id rather just ask people who know since im not smart enough to find stickys? lol. please help!

What are you're power goals? The headers become a bottleneck way down the line, the stock piece does reasonably good job.

Hmm not sure what headers are 2.5 to 3 inches lol ,the collectors are all the same size that bolt to the uppipe. Borlas are good , but do you really need headers? , myself I'd port the stock manifolds before going headers, I had borla headers on my 05 wrx and the sound is not that great esp when they're cold.

well im about to gut my up pipe and wire brush it out make it nice and clean. i was told getting maddad headers would be a good idea not a bad idea but i cant find any info on them to see if they are even for my car. im trying just get more power. how would that bottle neck it? will aftermarket headers be bigger flow for everything else?

i dont really have any set goal for my car. as i read on nasioc and see more people do mods that might catch my interest ill try it out. i want to run a vf43, 700cc injectors. fmic, tgv delete, turbo xs dp, straight back 3'', cai, walbro 255, catless up pipe. and really the next thing i see would be doing headers no? someone mentioned it to me at a meet the other night thats why im asking about it now
