Redback 2.5" Catback Exhaust with Rear Muffler Delete.
Category: Mufflers and resonators


The Redback K-RPM15695 is a 2.5in cat-back with a rear muffler delete, listed to fit the Holden Commodore VT, VX and VY (Series 1). Deleting the rear box on a 2.5in cat-back is the louder, freer setup for these earlier Commodores.
Removing the rear muffler takes out the box that does most of the quietening, so the K-RPM15695 exits louder and harder than a system that keeps it. At 2.5in the cat-back is sized for the standard or mildly worked Commodore rather than a big-bore build, and deleting the rear box opens that note up. The catalytic converter side isn't touched.
A cat-back runs from the catalytic converter back to the tailpipe. On the VT–VY Series 1 that's the 2.5in centre and rear pipework, here with the rear muffler deleted from the run. The factory cat stays where Holden fitted it, so it's the after-cat flow that changes.
It deletes the rear muffler, not the catalytic converter, so noise — not emissions hardware — is the consideration. A deleted rear box raises volume, and NSW stationary and drive-by noise limits apply for registration. Confirm the build and noise requirements with the workshop before fitting.
Oak Flats Muffler Men supplies and fits the K-RPM15695 in-house across the Illawarra. We align the 2.5in cat-back joint, route the rear without the muffler, set the hangers and check the tailpipe clears the bumper.
