Will a prodrive sports cat down pipe from a 2005 sti fit a 2003 2ltr wrx..
what mods would be needed to make it fit??

cheers

I fitted one to mine with no issues, only thing I need to do is fabricate a bracket to bolt it to the gearbox which will only be a small length of flat bent at 90 degrees. Without this I am getting a small exhaust knock when on bumpy roads and sometimes when reversing. I believe it is caused by the downpipe flexing whereas a bracket should hold it more secure.
