Redback STR145 is a cat-back exhaust listed to fit the Holden Commodore and Calais built from 07/2006 through 09/2015. Its recommended retail price is $271.99, and it changes only the rear half of the system, behind the catalytic converter.
Will the STR145 suit my Commodore or Calais?
This part is listed to fit Holden Commodore and Calais models across the 07/2006 to 09/2015 window — a long VE-into-VF span where the same family of platforms shared rear pipework. Because the listing covers both the workhorse Commodore and the better-trimmed Calais of that era, the body, engine and tailpipe arrangement can vary between them. Fitment feed data is not infallible, so we treat it as listed to fit rather than confirmed; send the workshop your build and we will match it against the STR145 listing before anything is ordered.
What is a cat-back, and what does swapping it actually do?
A cat-back is everything downstream of the catalytic converter — pipe, muffler and tailpipe — supplied as one rear section. Replacing it leaves the cat and front plumbing untouched, so it is the lighter-touch exhaust change rather than a turbo-back or engine-back job. The note typically comes up louder than the factory item; we do not quote a sound level because Redback hasn't published one for the STR145, and diameter and material aren't published on this listing either.
Is it road legal?
As a cat-back, the STR145 sits behind the catalytic converter and doesn't disturb the factory emissions hardware up front. Whether the finished car meets registration and noise rules still depends on your exact variant, 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 cat-backs in-house across the Illawarra. We verify the STR145 matches your Commodore or Calais, check the rear section clears the underbody and hangers, and book the bay once the variant is confirmed. Older Holden platform stock is often brought in to order, so check current availability with us.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Does the STR145 fit both the Commodore and the Calais?
- It's listed to fit the Holden Commodore and Calais built from 07/2006 to 09/2015. The two differ in trim and body, so confirm your exact variant with the workshop before ordering.
- Does it touch the catalytic converter?
- No — it is a cat-back, so it replaces the system from behind the catalytic converter rearward. The factory cat stays in place.
- What does it cost?
- The recommended retail price is $271.99. Send your build to Oak Flats Muffler Men and we'll confirm fitment before placing the order.
