The Exhaust Systems Australia RAM-DT-1500-5-7L-HEMI-VAREX-VALVED-CAT-BACK-EXHAUST-SYSTEM is the Varex valved cat-back for the newer DT-generation RAM 1500 with the 5.7L HEMI V8. The DT is the later truck — a separate listing from the earlier DS Varex system, at an RRP of $2,350.
RAM's 1500 sells here in two generations — the earlier DS and the newer DT — and the underbody changed enough between them that each gets its own cat-back. This is the DT version, with a Varex valved bi-modal muffler. A cat-back covers the run behind the catalytic converter, so the cat and the emissions hardware ahead of it stay factory; this is a rear-section job, not an engine-back rebuild. Diameter and material aren't published for the listing, so we confirm those at the workshop if they matter to you.
It's listed to fit the DT-generation RAM 1500 with the 5.7L HEMI — the HEMI Dodge has carried across these trucks. Getting the generation right is the key check here, since the earlier DS uses a different cat-back. As a special-order item, send your exact DT year and trim and we'll confirm the listing matches first. Feed data can be imperfect, so we read fitment as listed-to-fit rather than guaranteed.
Inside the muffler a Varex valve opens or closes a second path through it. Closed, the system runs a more restrained note; open, it lets a louder one through, typically switchable from the cabin. That gives the DT a quieter setting for everyday running and a bigger note on demand, rather than being loud all the time. We don't publish a sound level for this part, so we won't put a figure to it.
Oak Flats Muffler Men supplies and fits this valved cat-back in-house in the Illawarra. The rear section bolts to the factory exhaust and the valve control has to be wired in, so we check clearances over the DT's rear axle and confirm the switch operates cleanly before sign-off. RRP is listed at $2,350 AUD; as a special order we'll confirm lead time at booking.
