We’re drawn to Porsche’s performance cars because of their track record (literally) of exceptional engineering and performance, but even so they are prone to production shortcomings that we aim to address when possible. For their GT3 models of the 997 and 991 generations, we saw an alarming trend of center mufflers failing rather severely, sometimes without any additional modifications. As a company that holds great interest in driving these cars hard, as do our customers, we knew it was an opportunity to show our expertise and give drivers the peace of mind that their center muffler will not be a failure point, whether they have upgraded headers or no other upgrades at all. In a high-paced track environment, any precaution we can take to ensure longevity and safety is of the most importance. Sound is good too.

Our GT3 Center Muffler fits right in place of the factory unit, uses thicker gauge stainless steel, and provides a more durable solution for your GT3. Best of all, our Lifetime Warranty ensures that even if it does fail, it will be replaced at no cost. Replacing your failure-prone factory muffler could prove to be a much costlier exercise.

We offer our muffler replacement in two distinct variations, one that amplifies that naturally-aspirated flat-six and another that reduces overall volume in case you frequent tracks that employ strict sound limits.
