OEM Restriction

Factory C8 RS6 & RS7 downpipes include two large catalysts that restrict exhaust flow, limiting power output. Upgrading to ARM C8 RS6 & RS7 Downpipes eliminates this restriction, improving exhaust flow for increased performance.

CONSTRUCTION

Built from SS304 stainless steel, ARM C8 RS Downpipes ensure long-lasting strength and weld integrity. Starting at the turbochargers with a 5.75" CNC-machined V-Band flange, these downpipes seamlessly connect to OEM or upgraded turbos with the same exhaust housing size. A centering key in the V-Band guarantees perfect alignment with OEM or ARM C8 4.0T Midpipes.

The downpipes feature a full 304 Stainless Steel 5.5" body, tapering to 3" to connect with either ARM or OEM midpipes. For added convenience, the design incorporates a removable midpipe flange, significantly simplifying installation. This feature eliminates the hassle of securing hard-to-reach bolts, saving time and effort. Simply pre-install the midpipe flange, then attach the downpipe using a single, accessible exhaust clamp.
