The Redback STR125 is a 2.5in rear muffler finished with a dual tail pipe, listed to fit the V6 Holden Commodore VT, VX and VY in sedan, wagon and ute. The twin-exit tailpipe is the visual and packaging point of difference at the back of the car.

What does the dual tail pipe change?

STR125 carries a 2.5in body and exits through two tailpipes instead of one, giving the back of the Commodore a twin-outlet look in place of the single factory pipe. As a chambered rear muffler it still works by absorption and reflection to keep the V6 civil, so it's the quieter end of the spectrum with a tidier rear presentation.

Is 2.5in the right size for a V6 Commodore?

A 2.5in bore is a sensible match for the VT-VY V6 — large enough to ease the factory restriction without going oversized for a six-cylinder. It's the common upgrade size for these cars when you want a freer rear muffler that still keeps gas speed sensible on the street.

Will it suit my VT, VX or VY?

It's listed to fit the V6 Commodore VT, VX and VY in sedan, wagon and ute bodies. Those share a lot under the rear, but body and tow variations exist, so confirm your exact build with the workshop before ordering.
