The XForce E4-SW30-CBS is a cat-back exhaust listed to fit the Subaru Impreza G3 sedan across 2008–2011, with a recommended retail of $850. It's a rear-section system supplied and fitted at our Illawarra workshop.
The listing names the Subaru Impreza in sedan body across 2008–2011, and the slug ties it to the G3 generation. That gives us the make, body and year span to work from. The supplier doesn't break out the engine or trim, so confirm your exact G3 sedan with the workshop before ordering, since fitment feeds can be imperfect.
As a cat-back, the E4-SW30-CBS swaps the exhaust from the catalytic converter rearward — the centre run, silencing and tailpipe — and keeps the factory cat and front pipework in place. The diameter, material and muffler detail aren't published for this listing, so we read those off the kit at fitting rather than quoting figures the supplier hasn't given.
Because the change sits behind the cat, this is a back-half upgrade rather than a full engine-back one — a tidy install that alters the rear flow and the note without touching the emissions hardware. Expect a fuller sound than the factory system on the G3 sedan; we hold no sound data for this part, so that's as far as we'll go on character.
Oak Flats Muffler Men fits XForce cat-back systems in-house across the Illawarra. We offer the part up to your G3 sedan, confirm the rear pipework clears the underbody and hangers, and book the bay once it's verified. The recommended retail price is $850.
