Is the resonated mid exhaust section on a 2005 sti the same as all from 2001-2007? If so in theory and standard diameter mid section should fit. I have seen one i am after but also seen on other sites that there are differences, particularly when the 2.5 came about.

Any suggestions for good online exhaust gasket suppliers?

Any help appreciated.

 

I recently fitted a standard backbox from a 2003 STi to my 2006 when it failed the MOT.

Think they're all the same fitting.
