MPI Automotive DS Ram 1500 5.7L Hemi V8 Y-Piece To Suit Manta Headers And Single 3in Catback System.
Category: Extractors and headers


The MPI Automotive SSMBY275 is a Y-piece listed to fit the DS RAM 1500 with the 5.7L Hemi V8, made to join Manta headers to a single 3in cat-back system. It is the connecting pipe that merges the two header banks into one 3in run, not a full exhaust on its own.
A Y-piece is the junction that takes the two exhaust banks of a V8 and merges them into a single pipe. On the SSMBY275 that means collecting the flow from the Manta headers and feeding it into one 3in cat-back run behind it. It is a bridging part: it sets how the front of the system meets the back, so the header outlets and the single 3in pipe line up without an adaptor. By itself it changes neither the cat arrangement nor the muffling; it is the link between the two.
The SSMBY275 is cut to suit a single 3in cat-back, so the 3in figure is the pipe size it mates the rest of the system to. That makes it specific: it is designed around Manta headers at the front and a single 3in run at the rear, rather than a twin layout. If your RAM is set up differently, the Y-piece may not be the right link, which is why the matching parts matter as much as the vehicle.
The SSMBY275 is listed to fit the DS RAM 1500 with the 5.7L Hemi V8. Because it is built around Manta headers and a single 3in cat-back, confirm your header brand and system layout with the workshop before ordering, not just the make and model.
Oak Flats Muffler Men fits pipework like the SSMBY275 in-house across the Illawarra. The Y-piece has to sit square between the headers and the single 3in pipe so the joins seal and the system clears the underbody. Supplied by MPI Automotive at $645.43 AUD; send us your RAM's setup and we will confirm the Y-piece suits before booking the bay.
