Category: Complete exhaust systems


The Exhaust Systems Australia HOLDEN-HSV-GTS-GEN-F-2013-2017-XFORCE-TWIN-3-CATBACK-SYSTEM-RAW-409 is a twin 3in cat-back system listed to fit the HSV GTS Gen-F (2013–2017). It's a raw 409 stainless XForce-pattern system and a special-order item.
This is a cat-back run for the Gen-F GTS, replacing the exhaust from the catalytic converter back. It's a twin 3in layout in raw 409 stainless. The listing references the XForce dump-and-cat pattern, so it's built to mate up behind that front section rather than reinventing the whole system from the engine.
A cat-back system replaces the exhaust from the catalytic converter back to the tailpipe — the section after the emissions hardware. It's the milder of the common upgrades because it leaves the cat and everything ahead of it untouched, changing the rear silencing and pipe routing rather than the engine's breathing right off the turbo or manifold. On the Gen-F GTS that means new twin 3in rear pipework and silencing in raw 409 while the cat stays in place — louder than the standard HSV system rather than a full straight-through.
It's listed to fit the HSV GTS Gen-F across the 2013–2017 range. As a special-order item it's brought in to your build, so confirm your exact year and variant with the workshop before ordering — fitment data can be imperfect.
