The SOUL Center Muffler is designed for Porsche 997 and 997.2 GT3 owners who want a stronger, more durable replacement for the factory center muffler with the ability to choose either more exhaust volume or less exhaust volume than stock.
SOUL developed this system after observing failures of factory GT3 center mufflers, including cars that had not otherwise been heavily modified. For street and track-driven GT3s, a center muffler failure can become more than an inconvenience, particularly during sustained high-temperature use.
Rather than simply duplicating the factory component, SOUL uses thicker-gauge stainless steel construction and offers two distinct internal sound configurations. The Louder Than OEM version increases naturally aspirated flat-six presence, while the Quieter Than OEM version is specifically intended for owners who need additional sound control for tracks with restrictive noise limits.
The muffler bolts directly into the factory location without modification and can be used with otherwise stock exhaust components or as part of a more extensively modified GT3 exhaust system.
Fits 2006–2011 Porsche 997 / 997.2 GT3
Fits applicable 997 / 997.2 GT3 RS exhaust configurations
Compatible with both 997.1 and 997.2 GT3 generations
Compatible with naturally aspirated 3.6L and 3.8L GT3 engines, depending on model year
Direct replacement for the factory center muffler

SOUL offers two versions of the Center Muffler so the exhaust can be tailored around the intended use of the vehicle.
Louder Than OEM
The louder configuration is designed to amplify the GT3's naturally aspirated flat-six character compared with the factory center muffler.
This is the appropriate choice for owners who want increased exhaust presence while retaining an actual center muffler rather than moving to a Center Muffler Bypass.
SOUL Part Number: POR.GT3.MUFL
Quieter Than OEM
The quieter configuration is designed to reduce overall exhaust volume compared with the factory center muffler.
This version is particularly useful for GT3 owners attending tracks with strict sound limits or for vehicles with other exhaust modifications that have increased overall volume beyond the desired level.
SOUL Part Number: POR.GT3.MUFQ
SOUL developed this product after observing failures of factory GT3 center mufflers under demanding use.
On heavily driven street cars and track cars, repeated thermal cycling and sustained exhaust temperatures can place considerable stress on the center muffler assembly. Exhaust modifications such as higher-flow headers can further increase the demands placed on downstream components.
The SOUL Center Muffler uses thicker-gauge stainless construction to provide a more robust replacement while preserving a true muffled exhaust configuration.
This makes it particularly attractive for owners who want improved durability without converting the car to a complete center-muffler bypass.
Choose Louder Than OEM if:
You want more GT3 flat-six sound
You still want a true center muffler rather than a bypass
Your car retains relatively quiet factory headers and side mufflers
Track noise restrictions are not a major concern
Choose Quieter Than OEM if:
Your local tracks enforce strict sound limits
Your headers or other exhaust components have already increased volume substantially
You want additional sound attenuation without reinstalling the factory center muffler
Exhaust-system durability is important but additional volume is not
The SOUL Center Muffler retains actual sound attenuation and is available in either louder-than-stock or quieter-than-stock configurations.
The SOUL Center Muffler Bypass removes the factory center muffler entirely and provides a much more aggressive exhaust character along with approximately 11 lbs of weight reduction.
For owners prioritizing maximum sound and reduced weight, the Center Muffler Bypass is the more aggressive solution.
For owners prioritizing durability, controlled sound levels, or compliance with track noise restrictions, the SOUL Center Muffler provides the more appropriate solution.
There are no exhaust-tip variants associated with this product.
The SOUL Center Muffler is sold as a replacement center muffler assembly rather than as a center muffler/tip package, so the Squarespace product only needs the Sound Level selection.
