XForce Performance Exhaust System.
Category: Complete exhaust systems


The XForce E4-SW11-MP01CBS is a cat-back performance exhaust system listed to fit the Subaru Impreza from 1994. It's the rear-section upgrade, supplied and fitted at our Oak Flats workshop in the Illawarra.
This is a cat-back for the Impreza, replacing the exhaust from the catalytic converter rearward. The factory cat and front pipework remain; only the back section changes. XForce don't publish a diameter, material or muffler configuration for this part in our records, so we won't quote figures we can't verify — they're confirmed against the kit at fitting.
A cat-back sits behind the catalytic converter, so replacing it changes the rear flow and the exhaust note while the emissions hardware up front is left alone. On a Subaru like the Impreza it's the straightforward rear-section upgrade. Since the cat stays in place, the change is confined to the back of the system.
It's listed to fit the Subaru Impreza from 1994. We don't hold the exact series or engine for this part, and listing feed data can be imperfect, so read the fit as "listed to fit" and confirm your exact build with the workshop before ordering.
Oak Flats Muffler Men supplies and fits XForce cat-back systems like this in-house. We check the listed fitment against your Impreza, confirm the rear pipework clears the underbody and hangers, and book the bay. The recommended retail price is $799. Send your Impreza details and we'll confirm the build first.
