My cous has an 01 wrx with an afterburner back box and we have just read in an article in a subaru magazine saying that this particular model has 3 cats on it. Which is the best way to go without upsetting the ECU.... Centre section, front cat pipe or turbo downpipe, which has the biggest gains?

im confused over the whole 'cat' subject too. which bits are actually the cats? i understand that there are several sections, this is how i understand them to be, but don't know where 3rd cat is?

ENGINE
1. manifold
2. up-pipe
TURBO
3. downpipe (with cat)
4. cat pipe (with cat - obviously!)
5. centre section
6. back box
