Product Description

The MBRP S4611304 Muffler Bypass Exhaust Section is designed for 2010-2016 Audi S4 and S5 models equipped with the 3.0-liter TFSI B8/B8.5 engine, providing an upgrade over the factory muffler by removing or bypassing it to improve exhaust flow and deliver a more engaging exhaust note on throttle. Built from durable T304 stainless steel with 2.25" mandrel-bent tubing and a tour sound profile, this bypass exhaust enhances throttle response and exhaust dynamics without overly loud cabin noise, making it suitable for both spirited driving and daily use.

Installation involves cutting of the stock system at the muffler and incorporating the bypass section, with a supplied adaptor included for clean fitment on the Audi S4 where needed. The direct-fit design utilizes factory mounting points, and the T304 stainless steel construction backed by MBRP's lifetime warranty ensures long-term durability. Whether you're seeking a deeper exhaust tone, improved flow, or a performance-oriented upgrade from stock, the S4611304 delivers both functional gains and an enhanced sonic character specific to the Audi S4 and S5 platform.
