The Redback STR161CP is a cat-back performance exhaust system listed to fit the Holden Commodore from 2007. It's the rear-section upgrade, supplied and fitted at our Oak Flats workshop in the Illawarra.

What does this system cover?

This is a cat-back run for the Commodore, meaning it replaces the exhaust from the catalytic converter back to the tailpipe. The factory cat and front pipework stay in place, and only the rear section changes. Redback don't publish a pipe diameter, material or muffler spec for this part in our records, so we don't quote figures we can't back up — those details are confirmed against the kit at fitting.

What's a cat-back and what does it change?

A cat-back is the section behind the catalytic converter, so swapping it alters the rear flow and the exhaust note without touching the emissions hardware up front. It's a tidy, bolt-in style of upgrade rather than a full engine-back rebuild, which is why it's a common first step on a Commodore. Because the cat is left in place, the change is to the rear of the system only.

Will it suit my Holden Commodore?

It's listed to fit the Holden Commodore from 2007. Listing feed data can be imperfect and we don't have the exact series or engine recorded for this part, so treat the fit as "listed to fit" rather than a promise of fit — confirm your exact build, body and driveline with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Redback cat-back systems like this in-house. We check the listed fitment against your car, confirm the rear pipework clears the underbody and hangers, and book the bay. The recommended retail price is $218.99. Send your Commodore details and we'll confirm the build before the part is ordered.
