sti exhaust
Silly question probably, have a chance of an sti front and centre cat exhaust for £30. Reckon it makes any performance increase? There must be something in it, 40bhp dont just come from the ecu between wrx and sti?

Lee, have you fitted it yet? 
Not sure about the STI pipes with cats in, but why dont you get a decat unpipe and centre with out the silencer, this certainly gives some power gains without worring about MOT'S and CEL problems.
I'm sure someone will give you a whole lot more info.
