By reducing exhaust back-pressure, they let the 4.0T turbos spool faster for more power and torque — especially low in the rev range — and an incredible sound. The OEM downpipes use two large catalysts that choke flow; the ARM downpipes remove that restriction.\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGains of up to 41 whp \/ 45 wtq.\u003c\/li\u003e\n\u003cli\u003eFaster turbo spool and an improved exhaust note.\u003c\/li\u003e\n\u003cli\u003eFully reversible.\u003c\/li\u003e\n\u003cli\u003eRemovable midpipe flanges for easier installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConstruction\u003c\/h3\u003e\n\u003cp\u003eBuilt from SS304 with a 5.75\" CNC-machined V-band flange at the turbos (connects to OEM or upgraded turbos using the same exhaust-side housings), with a centering key to line up perfectly with the OEM or ARM C8 midpipes. The body holds a full 5.5\" until it turns toward the midpipes, gradually reducing to 3\". A removable midpipe flange saves serious install time — secure it to the midpipe first, then connect with a single, easy-to-reach exhaust clamp.\u003c\/p\u003e\n\u003ch3\u003eFitment (4.0T)\u003c\/h3\u003e\n\u003cp\u003eAudi C8 RS6, C8 RS7, D5 S8, D5 A8.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e 2x downpipes, 2x midpipe flanges, 2x exhaust clamps, 2x midpipe gaskets, 6x midpipe bolts, 6x midpipe nuts.\u003c\/p\u003e\n\u003cp\u003eBacked by ARM Motorsports' lifetime warranty against defects in craftsmanship and fitment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEmissions disclaimer:\u003c\/strong\u003e This product is not legal for sale or use on pollution-controlled vehicles operated on public roads and is intended for off-road, race, or closed-course competition use only.
