Left-and-right hotdog placement is what sets this version apart: the TWIN-3-INCH-CAT-BACK-EXHAUST-LEFT-AND-RIGHT-HOTDOGS-FOR-SRT-JEEP-GRAND-CHEROKEE- from Exhaust Systems Australia is a twin 3in cat-back for the SRT Jeep Grand Cherokee (2012–2021), with a hotdog resonator on each side.
What does left-and-right hotdog placement give you?
This version runs a hotdog resonator down each side — left and right — rather than centred. A hotdog is a compact straight-through resonator, so a pair on the twin 3in pipes controls tone without the restriction of a chambered muffler. Splitting them left and right keeps each bank's resonator on its own pipe, suiting the SRT's dual-pipe layout. It's a free-breathing setup with a harder note than an absorptive muffler would give.
What is a cat-back on the SRT?
A cat-back replaces the system from behind the catalytic converters back to the tail, leaving the emissions hardware in place. On the SRT Grand Cherokee that means twin 3in pipes carrying the side-mounted hotdogs back to the tips. There's no published sound figure, so the honest way to gauge it is to hear a comparable SRT fit before deciding.
Will it suit my SRT Grand Cherokee?
It's listed to fit the SRT Jeep Grand Cherokee across the 2012–2021 range. The twin routing and left-and-right hotdog positions are shaped for that body, so confirm your exact year and build with the workshop before ordering.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this twin 3in cat-back in-house across the Illawarra. We route both pipes, set the left and right hotdogs and align the tips even at the tail. Bring the Jeep in and we'll confirm fitment and book the bay.

Common questions
Where are the hotdogs mounted?
Left and right — one resonator on each side pipe, suiting the SRT's twin layout.
What years does it fit?
It's listed for the SRT Jeep Grand Cherokee 2012–2021. Confirm your exact year with the workshop.
Muffler or resonator?
Hotdogs — straight-through resonators — so it runs a harder, freer note than a chambered muffler.
