Pre-Muffler Delete Pipes – B9/9.5 S4/S5
Pre-muffler deletes for the B9/9.5 Audi S4/S5 (pre-order, next stock in production)
Add just the right amount of sound to your B9/9.5 S4/S5. These 304 stainless and mandrel bent pipes delete what Audi calls the “pre-mufflers” just after the downpipes. Adds approx 15-20% more volume to the exhaust while retaining the OEM resonator so there is no drone. Simple installation. Comes with high-quality stainless sleeve clamps.
