Redback Extreme Duty Exhaust.7L V8 DS Series (12/2018 - on) (SKU: DRX80100-PO) Engineered for a wide.
Category: Mufflers and resonators


Built for the petrol RAM 1500, the Redback DRX80100-PO is an extreme-duty exhaust listed to fit the 5.7L V8 (DS series, 2018-on). It's a heavy-vehicle exhaust pitched at the long-haul, high-load end rather than a tailpipe cosmetic.
Redback's extreme-duty line targets full-size American trucks that work — towing, loaded touring and the heat that comes with a 5.7L V8. The DRX80100-PO is the exhaust section listed for that DS-series RAM, sized for the engine's gas volume so the V8 breathes without the factory restriction. Redback hasn't published the bore, material or muffler configuration for this listing, so we don't quote figures we can't trace.
It's listed to fit the RAM 1500 5.7L V8, DS series, from 2018. The DS body covers a long production run with running changes, so send us your exact build and chassis details and we'll confirm the part matches before anything is ordered.
This listing doesn't specify a catalytic-converter delete, so we won't make a compliance claim either way. Emissions hardware and exhaust noise rules vary, and on a vehicle this size the details matter — confirm the road-legal build with the workshop before you commit.
Oak Flats Muffler Men handles big American trucks like the RAM 1500 in-house across the Illawarra. Redback supplies the exhaust; we check hanger positions, clearances around the heavy chassis and the tow setup, then book the bay once the fitment is confirmed.
