Then again, a larger diameter would mean less restriction so more flow, but whether there is enough extra flow for some more velocity in the larger pipe I dont know.

Anyone?

Where is the restriction in your current Up-Pipe ?

I'm sure there is no Cat in there anymore after all the problems Subaru had with them falling to pieces. Pretty sure only the 01-02 WRX's had the cat and then they were taken out again in the 03 WRX onwards ie catless up-pipe.

Leave it all as is and flog the catless up-pipe to a 01-02 WRX owner.

I was only referring to the diameter of the pipe. So if they are the same diameter there is definately no point.

Are they the same diameter?

if so then my question is answered
