Of course video does this exhaust no justice, but we wanted you to have something to listen to! In person the exhaust note was very deep, the exhaust pops A LOT louder, and the already beautiful exhaust note is even more so exaggerated.

If you are in the market for an exhaust system that wakes up your GT3 / GT3RS and takes it to a whole new level, yet don't want your neighbors to come running out after you every time you come home then you've come to the right place! The SSR Performance Competition Series Center Muffler Delete is the perfect tool to turn your car from "tame" to "savage" with just the click of a button!

With our Porsche 991.1 911 GT3 / GT3RS Competition Series Center Muffler Delete we really took our time to ensure that we were crafting a system that not only offered considerable value but also a system that offered a 100% unique experience. We are glad to say we believe we've achieved just that.

The SSR Performance Competition system is the first center muffler delete on the market that offers custom resonance mufflers that are hand built to custom specifications specifically just for our GT3 systems. With the tight tolerances that we had to work with when developing this system we had to get creative with the production of our mufflers. As it stands there aren't many (if any) center muffler deletes that offer the added benefits of mufflers when the factory valves on the side mufflers are closed. Why did we do this? We wanted to create a system that sounds stock when required and then completely savage with just the push of your factory center console exhaust button.

We hope that you can see why our system is one of the most highly reviewed systems on the market and choose SSR Performance for your exhaust today!

We guarantee that any exhaust we ship will fit on any 991.1 GT3 / GT3RS perfectly. We create our exhausts using a fitment jig which precisely defines the pathways the exhaust will follow down to the exact length and degrees of bend. The SSR Performance 991.1 GT3 / GT3RS Competition Series exhaust is a direct bolt-on replacement of your stock factory center muffler. Any hardware needed is included. Ceramic coated pipes can make for a tighter fit and may need more force during install due to extra thickness of the coating. 

Build and Design

We craft all of our exhausts using only certified 304 Stainless Steel. We chose 304 Stainless Steel because of its weldable properties, high corrosion / oxidation resistance, and relatively high toughness. The process of building these exhausts begins with the in-house engineering design work on our test 2015 Porsche 991.1 GT3. It then moves onto the precision CNC machining of our flanges and laser cut exhaust brackets. Lastly, it ends with the welding and beautiful brushed finish of the final product. This whole production process takes place in the USA and supports approximately 100 American jobs every single day.

Our tip reinforcement bracket was inspired by the exhaust tip design of the classic Porsche 930 Turbo.

With some inspiration and a little bit of imagination we created something that we think truly accentuates and differentiates our system.


We engineered our exhaust for optimal flow. We take pride in our education and do not hesitate to make it very clear that everything we create is designed and tested in CAD / CAM software much before it is ever fabricated into a real physical part. We have created a completely precision CNC machined mono-block V-band that is completely smooth and has no lip or step. We know how important it is for exhaust gases to pass through from the headers to the exhaust smoothly, so we took initiative and designed our downpipes in such a way that flow is maximized.
