The oval body is the point of difference here: the Everflo HOLDEN-COMMODORE-VT-VZ-5-7L-SEDAN-TWIN-3-REAR-OVAL-MUFFLER-EVERFLO from Exhaust Systems Australia is a 3in rear muffler with an oval body, listed for the VT–VZ 5.7L sedan twin system. The oval shape tucks the box up flatter for clearance under the rear of the car.

Why an oval rear muffler?

An oval body is flatter than a round one for the same volume, so it sits up tighter against the floor and lets the muffler clear the rear suspension and tank on a low-slung sedan. On the VT–VZ 5.7L this is the rear silencer of a twin system, built on a 3in bore to suit the LS-era V8 and a flow-minded layout. Being the rear box, it sets the final note at the tailpipe end after the front and centre stages have done their work.

What does the rear muffler do to the sound?

A muffler quietens by absorbing and reflecting sound inside its body, and in the rear position the Everflo shapes the tailpipe character you actually hear standing behind the car. On a 5.7L it tempers the V8's final note rather than the mid-range. There's no decibel figure published, so the honest way to judge it is to hear a comparable VT–VZ twin fit before you decide.

Will it suit my 5.7L sedan?

It's listed to fit the Holden Commodore VT through VZ 5.7L sedan running a twin 3in system. The oval rear box is shaped for the sedan's rear clearance, so confirm your exact model and that you're on the twin layout with the workshop before ordering — the ute and wagon sit differently at the back.

How do we fit it in the Illawarra?

Oak Flats Muffler Men supplies and fits the Everflo oval rear muffler in-house across the Illawarra. We hang it on the sedan's rear mounts, check the oval body clears the floor and suspension, and line it square to the pipe ahead of it. Bring the car in and we'll confirm fitment and book the bay.

Common questions

What makes this muffler oval?
It has an oval (flattened) body so it tucks up closer to the floor for better rear clearance on the low sedan, instead of a round body.
What bore is it?
It's 3in — sized for the 5.7L V8 and a twin, flow-built system.
Is it the front or rear muffler?
It's the rear box, so it sets the final tailpipe note. The front and centre stages are separate.
