The ARM C8 RS Downpipes instantly boost power, torque, and throttle response for your 4.0T-powered Audi C8 RS6, RS7, or D5 S8 A8. By improving exhaust backpressure, these downpipes enable faster turbo spool, delivering more power and torque, especially in the lower RPM range—all while enhancing the exhaust note!

HIGHLIGHTS

• Gain up to 41whp / 45wtq
• Faster Turbo Spool
• Improved Exhaust Note
• Fully Reversible Design
• Removable Midpipe Flanges for Easy Installation

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.
