This Subaru Impreza performance exhaust is made in 2.25"/57.1mm pipework and fits from the catalytic converter section back to the centre section.
The resonated exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version which is a louder option as it excludes the centre silencer and therefore, has a sportier exhaust note.
