Redback STR174L is the left-side cat-back component listed to fit the Holden Commodore from 07/2006. It carries an RRP of $247.99 and forms one half of a dual-bank rear exhaust.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the STR174L in-house across the Illawarra. Because the L denotes the left side of a pair, the first thing we check is that the matching right-side piece is on hand — fitting one bank without the other isn't a complete job. From there we offer the section up, confirm it clears the underbody and the hangers hold it square, and book the bay once the build is matched.

What is a cat-back component, and why a left side?

A cat-back is the rear of the exhaust behind the catalytic converter. On a dual-bank layout that rear section splits into a left and a right piece, and the STR174L is the left one — supplied as a component rather than a whole system. The cat and front plumbing stay factory. Redback hasn't published the diameter or material for the STR174L on this listing, so we confirm those on the bench.

Will it suit my Commodore?

This listing covers the Holden Commodore from 07/2006. Fitment feed data can be imperfect, so it's listed to fit rather than guaranteed — give the workshop your exact engine and body and we'll confirm the STR174L, and its right-side partner, against your build.

Is it road legal?

As a cat-back component, the STR174L doesn't remove or alter the catalytic converter, so the factory emissions hardware stays in place. Road compliance and noise still depend on the specific car, so confirm NSW requirements with us before booking.
