Hotdog resonators in place of mufflers are what give this SRT cat-back its harder note: the TWIN-3-INCH-CAT-BACK-EXHAUST-WITH-LEFT-AND-RIGHT-HOTDOGS-FOR-SRT-JEEP-GRAND-CHER from Exhaust Systems Australia is a twin 3in system for the SRT Jeep Grand Cherokee (2012–2021), running left-and-right hotdogs.
What sound character do the hotdogs give?
Because this system silences through hotdog resonators rather than chambered mufflers, the note sits harder and freer. A hotdog is a compact straight-through resonator that trims tone without the flow restriction a muffler adds, so on the twin 3in SRT pipes the pair keeps the system open. It's the choice for an owner chasing more note from the V8, not a quieter result. There's no published sound figure, so hear a comparable fit before deciding.
How is the system laid out?
It runs twin 3in pipes the length of the cat-back with a hotdog on the left and one on the right, matching the SRT's factory dual layout. As a cat-back it replaces the system from behind the catalytic converters back to the tail and leaves the emissions hardware in place, so the factory converters stay.
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 side-mounted hotdogs 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 tail. Bring the Jeep in and we'll confirm fitment and book the bay.
