Redback STR174R is the right-side cat-back component listed to fit the Holden Calais and Commodore, plus the HSV Clubsport and Senator, built from 2006 to 2016. Its recommended retail price is $241.99.

Will the STR174R suit my Calais, Commodore, Clubsport or Senator?

This right-side part lists across four Holden-platform vehicles from 2006 to 2016 — the Holden Calais and Commodore, and the HSV Clubsport and Senator. The two HSV models are the performance and luxury-performance variants, and they carry their own rear pipework, so a listing covering all four is the starting point for matching rather than a guarantee. Tell the workshop your exact model and build year and we'll confirm the STR174R against it before ordering.

What is the STR174R, and what does the R mean?

The STR174R is a cat-back component, and the R marks it as the right-side piece of a dual-bank rear exhaust — the partner to a corresponding left-side part. It covers the rear of the system behind the catalytic converter; the cat and front plumbing stay factory. Redback hasn't published a diameter or material for the STR174R on this listing, so we don't quote figures we can't trace to the part.

Is it road legal?

Because the STR174R is a cat-back component, it doesn't touch the catalytic converter, so the factory emissions hardware stays in place. Final registration and noise compliance depend on the specific vehicle, so confirm any NSW requirements with the workshop before booking.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Redback parts in-house across the Illawarra. As the STR174R is the right side of a pair, we confirm the matching left-side piece is on hand, check both clear the underbody and 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.
