Exhausting question, but i need to know?
 

Right ppl just a quick one, i want to replace the c/c and b/b on my 06 wrx to free up some burble. Would it be ok for me to replace these parts with a 3'' bore or would i have to stick with the 2.5'' like the rest of the system, would this do any harm?
Advice would be gratefully recieved, thanks.. :wonder:

Do the 2.5" flange to 3" flange meet up correctly to bolt up?

he he flange

Thanks ppl.:)

:norty: :lol1:
do you get pink flanges on an sti :wonder: :norty: :lol1:
sorry i had to ask im a little tipsy and being a muppet, please ignore me :o

Put it this way, a well designed 2.5" is the best bet for up to ~350bhp (turbo response should be better the a 3").

Therefore, IMHO, it just a question of if you ever plan on going beyond this level..;)
