Porsche 911 (992 Chassis) GT3/GT3 Touring [2019+]

Here it is, the first ever Meisterschaft exhaust system designed and developed for the 911 Turbo! We begin our endeavor into 911 Turbo exhaust development with the all new 991 chassis Turbo S.


We started off by gathering a baseline test of the 991 Turbo S on our in-house Mustang Dyno, finding some very respectable stock power figures: 457 horsepower and 454 torque at its four wheels. After baseline testing was done, it was time to begin disassembling the brand new beast so that we could study the imperfections of the factory system and make our improvements.

The Super GT


Our answer is the ultra lightweight Meisterschaft Super GT, sporting 4 of our 102mm signature round split tips to give the back end an aggressive and complete new look. Our Super GT system replaces the overweight and restrictive OE muffler system with a 76mm high-flow X-Pipe engineered to provide maximum performance, especially once paired with our optional catalytic bypass pipes.

The Results

With a monstrous torque gain of 57 ft/lbs, a horsepower gain of 17 hp, and a weight saving of 21 lbs, the Meisterschaft Super GT is an all around win. Not to mention the exhilarating sound of the twin-turbo flat-6 violently breathing through the new exhaust, and even occasionally letting out a flame or two!

Sound, performance, and build quality. Since the beginning, we at GTHAUS have strived to set our brand above the rest, we’ve done so by combining these key components: Sound, Performance, Build Quality.


Meisterschaft Premium exhaust systems utilize traditional and modern styling to create the world’s most advanced exhaust system. From the high polish exterior finish to the marvelous hand welds, Meisterschaft exhaust systems look as beautiful as they sound..


Second to none. Meisterschaft, MUSA, and American Roar Racing exhaust systems provide the most unique exhaust notes that you’ll find in the industry, period. Our exhaust systems are custom tailored to each specific vehicle without the use of any universal parts. Countless hours of R&D are undergone to achieve pitch perfection from each vehicle. The result is an exhaust system that is as well tuned as a fine musical instrument, delivering an exotic, unique, and aggressive sound.


Our Meisterschaft, MUSA, and American Roar Racing exhaust systems are engineered to provide maximum power gain at the wheels. Power gains are realized using a state-of-the-art all-wheel-drive Mustang Dynamometer at our in-house research and development facility. Performance can be maximized if Meisterschaft rear muffler sections are used in conjunction with optional mid-pipe section(s) and/or catalytic replacement section(s).


The GTS (Ultimate Performance) exhaust systems are engineered for enthusiasts who want a no nonsense exhaust system that will perform and produce a superior sound at all times.

GTC (EV Control) exhaust systems are the world’s most technologically advanced units on the market. The GTC exhaust system utilizes electronic valves which control the “open” and “close” functions of the exhaust system. This allows the user to control the sound level, exhaust back pressure, and overall vehicle performance.

Build Quality

Meisterschaft, MUSA, and American Roar Racing exhaust systems are 100% hand-built. Each exhaust system is carefully TIG-welded by our artisan fabricators using only the best available materials. Our stainless steel (SUS) systems are produced using Type 304 stainless steel and high grade titanium alloy for our Titanium (Ti) exhaust systems.Using high grade materials enhances the durability and lifespan of the exhaust system.

As such, Meisterschaft exhaust systems do not suffer from corrosion when exposed to the elements, so there’s no need to worry about rust developing over time. Meisterschaft exhaust systems utilize the highest quality and most durable glass wool pack. Using the best materials allows Meisterschaft exhaust systems to endure the extreme temperatures and conditions it faces on a daily bases which aids to the longevity of the exhaust systems.
