Soul Performance POR.991GT3.SMB Side Muffler Bypass Pipes Non-Valved

The Soul Performance POR.991GT3.SMB side muffler bypass pipes (non-valved) replace the factory side mufflers on the Porsche 991.1 / 991.2 GT3. Removing the side mufflers cuts weight, reduces heat in the engine bay, and helps keep the rear tires cooler. It also gives a louder, more race-derived exhaust note.

Key Features:

• Weighs 38.3 lbs less than the factory exhaust components it replaces
• Large 3" mandrel-bent primary piping to increase exhaust flow
• Built from T304L stainless steel tubing with a 0.065" wall thickness
• Flex bellows make installation easier and help prevent cracking under extreme racing conditions
• Enlarged opening into the secondary pipe equalizes pressure in the center muffler, which reduces the chance of it cracking
• Non-valved design

These bolt-on bypass pipes give a noticeable increase in volume and cabin presence, with a more exotic exhaust tone.
