Unlock the performance of your Audi B9 S4 or S5 with the SPOOL Race Downpipes. Designed as a direct bolt-on replacement for the restrictive factory downpipes, they improve exhaust flow, reduce backpressure, and deliver quicker turbo spool, sharper throttle response, and a deeper, more aggressive exhaust note.
Manufactured from premium T304 stainless steel with precision TIG welds and smooth mandrel bends, the SPOOL Race Downpipes are built to handle high-boost applications while providing an OEM-like fit and long-lasting durability—all without the premium price tag.
