 Product Description

Fabspeed Porsche 991 GT3/GT3RS Side Muffler Bypass

Replaces the heavy and restrictive factory side mufflers for improved exhaust flow, increased sound and weight savings. Includes robust Helical valves which maintain the factory sound level adjustment for ultimate combination of performance and comfort.

Utilizing premium Helical valves along with the addition of O2 bungs, Fabspeed's Side Muffler Bypass Pipes provide the ultimate track solution for the 991 GT3 / GT3 RS. When accompanied with our new Long Tube Competition Headers, our Side Muffler Bypass Pipes allow the maximum amount of exhaust flow possible from the 991 GT3 / GT3 RS engine.

HELICAL VALVES

We chose to use Helical Valves on our 991 GT3 / GT3 RS track exhaust systems for their unprecedented quality - which have been proven by many OEM manufacturers such as McLaren, Ferrari, Lamborghini, and many more. Helical valves are an integral part of our Side Muffler Bypass pipes, opening and closing with precision to control the gas flow and optimizing engine back-pressure for improved performance. Helical’s extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs and high-temperature bearings at both ends of the butterfly spindle.

O2 BUNGS

We relocated the O2 bungs from the collector of the headers to the Side Muffler Bypass Pipes in order to maintain factory-like functionality with our Long Tube Competition Headers - allowing them to read all cylinders while maximizing the performance of the collector. This design will replace our existing SMBP’s allowing you to upgrade to our Long Tube Race Header design at any time in the future.
