Redback STR174L is the left-side cat-back component listed to fit the Holden Commodore and Calais, plus the HSV GTS and Clubsport, built from 07/2006 to 09/2015. Its recommended retail price is $247.99.
What is the STR174L, and what does the L signify?
The STR174L is a cat-back component — part of the rear exhaust behind the catalytic converter — and the L marks it as the left-side piece of a dual-bank arrangement, paired with a corresponding right-side part. It covers the back of the system rather than the cat or front plumbing, which stay factory. Redback hasn't published a diameter or material for the STR174L on this listing, so we confirm those against the part rather than quoting unverifiable numbers.
Will it suit my Commodore, Calais, GTS or Clubsport?
This left-side part lists across four Holden-platform vehicles from 07/2006 to 09/2015 — the Holden Commodore and Calais, and the HSV GTS and Clubsport. The HSV performance models run their own rear arrangements, so the broad listing is a starting point for matching, not a promise. Tell the workshop your exact model and build year and we'll confirm the STR174L against it before ordering.
Is it road legal?
Because the STR174L is a cat-back component, it sits behind the catalytic converter and doesn't disturb the factory emissions hardware. Whether the finished car meets registration and noise rules depends on the variant, so confirm any NSW requirements with the workshop first.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Redback parts in-house across the Illawarra. Because the STR174L is the left side of a pair, we confirm you have the matching right-side piece, 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.
