How old a Commodore is the STR101 listed for?

It is listed to the 1986 Holden Commodore — a first-generation car by year. Confirm your exact engine and body with the workshop, as records on cars this age can be imperfect.

Does it touch the catalytic converter?

No. As a cat-back it only replaces the pipework behind the converter; the cat and the engine-side run stay as they are.

The recommended retail is $252.99. We confirm fitment against your specific Commodore before ordering.

The Redback STR101 is a cat-back exhaust listed to fit the Holden Commodore from 1986, carrying a recommended retail of $252.99. It is the rear half of the system — everything behind the catalytic converter — for this first-generation Commodore.

Which Commodore era does the STR101 cover?

This listing pins the STR101 to the 1986 Holden Commodore, an early car by year. It is the rear-of-system part: the run from the converter back through to the tailpipe. The supplier does not publish a diameter, material or muffler layout for this particular kit, so we leave those blank rather than guess and confirm them against the physical part when it lands.

What does a cat-back actually replace?

A cat-back swaps the pipework and muffler sitting behind the catalytic converter, leaving the cat and the engine-side run untouched. On a car of this age it is usually the half that has rusted or split, so a fresh Redback section tidies the back end and shifts the note over a tired factory system. There are no power or sound figures recorded against this part, so we describe it for what it is rather than quoting numbers we do not hold.

Will the STR101 suit my 1986 Commodore?

It is listed to fit the 1986 Holden Commodore. The supplier does not split out engine or body in this listing, and feed data on cars this old can drift, so treat it as a guide. Send us your exact build — engine, body and any earlier exhaust changes — and we will check the STR101 against it before anything is ordered.

What does fitting an older cat-back involve here?

Oak Flats Muffler Men supplies and fits Redback sections like this across the Illawarra. On a 1986 car the work is as much about the surrounding hangers and flanges as the new pipe, so we put it on the hoist, check how it mates to your existing front pipe and converter, and fit it leak-free. The recommended retail price is $252.99; we confirm fitment against the listing before booking the bay.
