Product Description

The Fabspeed Side Muffler Bypass Pipes for the Porsche 997 GT3 and GT3 RS are precision‑engineered rear exhaust upgrades that remove the restrictive stock side mufflers to liberate exhaust flow, reduce weight, and deliver a more visceral flat‑six soundtrack. Mandrel‑bent from T304L stainless steel with CNC precision, these bypass pipes significantly increase exhaust throughput, reducing backpressure for sharper throttle response and stronger mid‑range torque delivery. They maintain compliance with factory tips while adding pronounced character under acceleration and create a distinctly track‑focused exhaust note without excessive drone. Ideal as a standalone upgrade or as part of a full performance exhaust build, these bypass pipes elevate both performance and auditory presence for your 997 GT3 or GT3 RS.
