RAM DS 1500 5.7L V8 Extractors And Cats kit, To Bolt To Factory Exhaust Or Manta 3in Single Catback for selected vehicle applications.
Category: Extractors and headers


The MPI Automotive SSMKRA0003 is an extractor-and-cat kit listed to fit the RAM DS 1500 5.7L V8, designed per the listing to bolt to the factory exhaust or to a Manta 3in single cat-back. At $3,919.22 RRP it is the front-of-system half of the equation, sized at 3in.
This kit covers the front of the system on the 5.7L V8 RAM DS 1500: the tubular extractors and cats. The listing notes it is built to bolt either to the factory exhaust or to a Manta 3in single cat-back, so it is the upstream piece you pair with whichever back-end you keep or add. It is recorded here as a 3in cat-back configuration; we confirm the join arrangement against your truck at fitting.
Extractors replace the cast factory manifolds with tubular primaries so each cylinder clears its gas more cleanly off the head. They sit at the very front of the system, ahead of the cats, so they set the path everything downstream follows. The honest trade-off is packaging — tubular extractors run close to surrounding components and need careful clearance and sealing, which is why this is a workshop fit.
It is listed to fit the RAM DS 1500 with the 5.7L V8. Because this kit is designed to mate to either the factory back-end or a Manta 3in single cat-back, the build of your existing system matters — confirm with the workshop what you are joining to before ordering.
Oak Flats Muffler Men fits extractor and cat kits like this in-house across the Illawarra. The key step here is the join: we confirm whether you are bolting to the factory exhaust or to a Manta 3in single cat-back, set the extractor clearances and seal each section. Tell us your back-end plan and we will book it in.
