VT-VZ Commodore Sedan Twin 2.5" Cat Back 409 Stainless Front Muffler Varex Dual 3" Polished Stainless Rear Special order.
Category: Mufflers and resonators
This twin 2.5in cat-back for the Holden Commodore sedan (VT-VZ) pairs a 409 stainless front muffler with a Varex valved, polished-stainless dual 3in rear — so it quietens up front and switches between mild and loud at the back. Supplied by Exhaust Systems Australia as a special-order item.
This system splits the job: a fixed 409 stainless front muffler does steady quietening mid-front, while the Varex bi-modal rear muffler adds a valve at the tail. Closed, the rear takes the muffled path for a calmer cruise; open, it diverts to a freer route for a louder note. The front box keeps a baseline of refinement so the car never gets raucous even with the valve open.
It's a twin 2.5in cat-back through the body, opening to a dual 3in at the polished-stainless rear. That replaces the system from behind the catalytic converter rearward, leaving the cat in place — a rear-system upgrade for the sedan rather than an engine-back change.
It's built in 409 stainless with a polished-stainless rear section for a brighter finish where it shows. As a special-order item the system is made to order, so lead times apply — confirm availability with the workshop when you book.
It's listed to fit the Commodore sedan across VT to VZ. Oak Flats Muffler Men fits valved cat-backs like this in-house in the Illawarra, including the valve control. Exhaust Systems Australia lists it at $1,499; confirm your exact build and the special-order lead time with us first.
