The Redback RPC101B is a performance cat-back exhaust system listed to fit the Holden Commodore from 1990. It's the rear-section upgrade for the VN-era Commodore.

What does a cat-back cover on the Commodore?

A cat-back replaces the exhaust from the catalytic converter rearward — pipework, muffler, resonator and tailpipe — and leaves the emissions hardware in front of it standard. On an early-90s Commodore that rear section is the sensible place for an exhaust change, altering the note and rear flow without touching the cat.

What's the trade-off with this kind of system?

A cat-back works only on the back half of the exhaust, which makes it the contained option next to a turbo-back or engine-back run. The supplier doesn't publish the diameter, material or muffler configuration for the RPC101B, so those are confirmed on inspection. On a car of this era, condition of the surrounding pipework matters too, and we check that on the hoist.

Will it suit my Holden Commodore?

It's listed to fit the Holden Commodore from 1990 — the VN era. Given the age, the exact build and what's already been changed underneath matter, so send your car through and we'll match it against the listing. Listing data can be imperfect, so confirm the build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Redback cat-back systems across the Illawarra. On an older Commodore we check the condition of the joins and hangers as we go, confirm the listing against your car and book the bay. The RRP is $589.
