Redback Exhaust.7L V8 VT VX VY VZ And VZ V6 Or Supercharged Sedans - Cat Back with Hotdogs & Rear Muffler Delete
Category: Mufflers and resonators

Running twin hotdog resonators ahead of a rear muffler, the Redback K-RPM15781 is a cat-back exhaust listed to fit the 5.7L V8 Holden Commodore across the VT, VX, VY and VZ sedans (and VZ V6 or supercharged). The hotdog-plus-muffler layout is the point of difference: it keeps drone in check while letting the LS V8 breathe.
The hotdogs are straight-through resonators that target resonance in the centre run, while the rear muffler handles overall volume at the exit. Combined, the K-RPM15781 aims for a freer-flowing cat-back that still travels quietly enough for daily use — the V8 note comes through without the constant boom a muffler-delete setup brings.
A cat-back swaps everything from the catalytic converters back to the tailpipe. On these VT–VZ sedans that frees up the section where the 5.7L LS engine benefits most without disturbing the factory emissions equipment up front. The cat stays where Holden put it.
It's listed for the 5.7L V8 Commodore sedan across VT, VX, VY and VZ, and also the VZ V6 or supercharged sedan. That's a broad family, so confirm your exact series and engine with the workshop so we match the correct centre and rear sections before ordering.
Oak Flats Muffler Men supplies and fits the K-RPM15781 in-house. We line up the cat-back joints, position both hotdogs and the rear muffler, set the hangers and check clearance along the sedan floor and over the rear axle.
