exhaust help
 

hi i have a 2002 wrx with cat back not sure what system is on but i would like to keep this system and work forward to the turbo changing the exhaust but not sure what i need theres a bit of confusion on my part regarding the up pipe down pipe and decat:o could some1 point me in the right direction even a diagram of the exhaust system would be great tried to find one but to no eval:thumb:

hi
you have three cats
one in the uppipe for cold start.(best replacing with sti up pipe)
One in the down pipe from turbo
one half way down the exhaust (centre pipe)
I'm not sure what else you need to know but i hope this helps

many thanks thats sorted the confusion out muchly appreciated:thumb:

the centre pipe is a resonator not a cat
