Will the exhaust offered from the dealer for the WRX (i believe its the STi Genome exhaust without the writing on it) fit on the STi or are the pipe diameters different? I had one on my '02 WRX; the look was great and the note was just perfect. - Thanx

The pipe diameters are different but the flange is the same and will bolt up. Assuming its the same muffler I saw a few months ago the piping is narrower then stock by about a quarter inch.

So then i will actually loose airflow by putting this on? Sounds to me like its not the best idea then.

Unless its a different exhaust yes you will lose airflow. I have seen about 4 different mufflers that is reffered to as the genome or the one on the s202(which is supposed to be the genome) But even if it did improve airflow I wouldnt reccomend it. You can buy a turbo back for what subaru charges for it.
