The XForce ESSW28CS is a race cat-back exhaust listed to fit the Subaru WRX STI G3 (VA) sedan. It replaces the pipework from the catalytic converter rearward, supplied by XForce and fitted at our Illawarra workshop.
As a cat-back, the ESSW28CS replaces the exhaust from the catalytic converter back, keeping the factory cat in place. The slug records it as a race cat-back for the WRX STI G3 (VA) sedan. XForce does not publish the diameter or material for this listing, so we confirm those against the part at fitting rather than quoting figures we cannot see.
A race cat-back is a less restrictive rear-of-cat system aimed at performance use. On a flat-four like the STI it changes the back half of the system and the note relative to the factory parts, while leaving the emissions hardware up front standard. The 'race' designation in the slug points to a freer-flowing build rather than a touring-quiet one — we will talk you through what that means for road use on your car before fitting. We do not quote sound or flow figures, as none are published here.
It is listed to fit the Subaru WRX STI G3, the VA-generation sedan. That model and body are recorded in the listing, but the supplier does not break out the full sub-variant detail, so confirm your exact build with the workshop before ordering. Fitment feed data can be imperfect.
