The Redback STR131 is a rear muffler with a twin tail pipe, listed to fit the 5.7L V8 Holden Commodore VT, VX, VY and VZ sedan. It keeps a real rear muffler in the system and exits through two tailpipes.

What does this twin-tailpipe rear muffler do?

Unlike a straight delete pipe, the STR131 retains a chambered rear muffler and finishes through two tailpipes, so it does real quietening work on the V8 while giving a twin-outlet rear look. It's the option when you want the dual-exit appearance and a freer rear, but still a controlled note rather than a raw, open exit.

Who suits a twin-exit rear muffler?

On the 5.7L V8 VT-VZ sedan, this suits an owner after the twin-tailpipe presentation and a lift over the tired factory rear, without going to a full muffler delete. The chambered muffler keeps the V8's note in check, so it reads as a sharpened factory sound rather than an all-out loud setup. We won't put a decibel figure on it.

Will it suit my VT-VZ V8 sedan?

It's listed to fit the 5.7L V8 Commodore VT, VX, VY and VZ sedan. Confirm your car is the V8 and send your exact build to the workshop, and we'll match the rear section before ordering.
