Redback STR173HD is a cat-back exhaust listed to fit the Holden Commodore VE and VF in Sedan and Wagon body styles. It carries an RRP of $438 and is the heavy-duty companion to the STR173 in this Redback range.
What does the STR173HD cover, and what does HD mean here?
The STR173HD is a cat-back — the rear of the exhaust behind the catalytic converter, supplied as pipe, muffler and tailpipe. The HD in the part number marks it as the heavy-duty version of the STR173; beyond that the supplier hasn't published a diameter or material on this listing, so we don't state specifics we can't trace. The cat and front plumbing stay factory, so it is a rear-section change rather than a full engine-back job.
Will it suit my VE or VF Commodore?
This part is listed specifically for the Holden Commodore VE and VF generations in Sedan and Wagon bodies. That is a tighter listing than the year-range parts in the range, but the Sedan and Wagon run different rear sections, so the body style matters. Tell the workshop whether yours is a Sedan or Wagon and which generation, and we'll confirm the STR173HD against it before ordering.
Is it road legal?
As a cat-back, the STR173HD leaves the catalytic converter and the factory emissions hardware in place. Final registration and noise compliance still depend on your specific car, so confirm NSW requirements with the workshop before booking the bay.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits the STR173HD in-house across the Illawarra. We match it to your VE or VF body style, check the rear section clears the underbody and sits square in the hangers, and book the bay once the build is verified.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- What's the difference between the STR173HD and the STR173?
- The HD is the heavy-duty version, listed for the Commodore VE and VF in Sedan and Wagon bodies. Both are cat-backs at an RRP of $438.
- Does it fit both the Sedan and the Wagon?
- It's listed for Sedan and Wagon VE/VF Commodores, but the two run different rear sections — confirm your body style with the workshop first.
- Does it keep the catalytic converter?
- Yes — it's a cat-back, so the factory cat stays in place.
