Twin rear hotdogs are the whole point of the HOLDEN-COMMODORE-VT-VZ-5-7L-SEDAN-TWIN-2-1-2-REAR-HOTDOGS, a 2in rear section listed to fit the Holden Commodore VT-VZ 5.7L sedan — the louder, free-flowing rear rather than a chambered muffler set.
What does a twin rear-hotdog set do?
Supplied by Exhaust Systems Australia, a hotdog is a compact straight-through resonator, so it flows more freely and runs a harder, louder note than a chambered muffler. As a twin rear set on the 5.7L sedan, this part gives the LS-era V8 a freer, more vocal rear exit, trading some quiet for flow and character. It is the loud-leaning rear option against the everflo-muffler version.
Where does it sit in the system?
This is the rear stage only, not a full cat-back, supplied as a twin hotdog set to bolt in at the back of a VT-VZ 5.7L sedan. At 2in it matches the sedan layout, and as a twin set it suits the dual rear of that car or an owner building a system in sections.
Will it suit my VT-VZ 5.7L?
It is listed to fit the Holden Commodore VT-VZ 5.7L sedan. The VT-to-VZ rear floor and hanger points vary, so confirm your exact series and that your car is the 5.7L with the workshop before ordering.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits these rear-hotdog sets across the Illawarra. We match the twin hotdogs to your existing pipework, set the hangers level, and check tailpipe clearance to the bar before you drive away. Listed at $200 as a rear set, its material is not published by the supplier; we match the twin hotdogs to your existing run rather than assume the grade.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
Are hotdogs louder than mufflers?
Generally yes. A hotdog is a straight-through resonator that flows more freely and runs a harder note than a chambered everflo muffler.
Is this the full exhaust?
No, just the twin rear-hotdog stage for the VT-VZ 5.7L sedan, not a complete cat-back kit.
