The Redback STR101 is a cat-back exhaust system listed to fit the Holden Commodore and Calais. It replaces the exhaust from behind the catalytic converter rearward, leaving the factory emissions hardware in place.
What is a cat-back system and what does it change?
A cat-back system replaces the pipework, muffler and tailpipe from the rear of the catalytic converter back to the tip — everything downstream of the cat, but nothing upstream of it. Because the catalytic converter and the front of the system stay factory, it changes the back half of the exhaust rather than the engine-out plumbing. That keeps the emissions equipment the Holden Commodore left the factory with, while replacing the rear section as a single supplied unit. The supplier hasn't published the diameter, material or muffler details for the STR101 in our data, so those are confirmed against the part on the bench.
Will it suit my Holden Commodore?
This STR101 is listed to fit the Holden Commodore from 1986. It's listed across related Holden models — Holden Commodore and Calais — from the same platform and era. Feed data can be imperfect, so it's listed to fit rather than guaranteed — send your exact build and we'll confirm the variant before anything is ordered.
Is it road legal?
As a cat-back, the STR101 sits behind the catalytic converter and doesn't remove or alter the factory cat, so the original emissions hardware stays in place. Whether the finished fitment meets registration requirements still depends on your exact vehicle and the noise rules that apply, so confirm the details and any state requirements with the workshop before booking.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits Redback systems like this in-house across the Illawarra. We check the part against your actual Commodore, confirm the hangers and clearances line up, and book the bay once the variant is verified. The listed RRP is $252.99 AUD; older-platform cat-backs like this are often brought in to order, so check current availability with us.
