These S68T downpipes are the newest addition to the G90 M5 collection and represent the same approach that built the reputation: eliminate the restriction, keep the car street legal, and require nothing from the tune.\u003c\/p\u003e\n\u003cp\u003eManufactured in-house in Miami, Florida from 304 stainless steel and TIG-welded throughout, each downpipe uses a cast upper stainless V-band for precise, repeatable fitment, then tapers from a factory-matched offset inlet into a 3” mandrel-bent body. The lower mid-pipe section is included. The assembly accepts the OEM O2 sensor heat shield, so the bay keeps its factory look.\u003c\/p\u003e\n\u003cp\u003eA pair of 5” GESI Ultra High Output catalytic converters does the emissions work, with a 400 cell per square inch substrate furnace-brazed to a 304 stainless mantle. GESI cats are EPA registered and fully OBD2 compliant, and they will not throw a CEL for catalytic efficiency.
