I have my TXS exhaust left over from my 02 WRX. Will it fit the STi?

I also have a Cusco header (not twin scroll, obviously), uppipe, and FP20G. I will need these items if I want to use the 20G, correct?

Thanks in advance!

Steve

it will fit

Yeah, it will fit thats the same thing I did when going up to my05...regarding the 20g, all you need to install the 20g is EM, injectors, fuel pump...the STi's uppipe is already catless, so you dont NEED to keep the header/uppipe unless you want to..enjoy the new car man:D
