Why GTHAUS?

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, and Build Quality.

Style

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 marvellous hand welds, Meisterschaft exhaust systems look as beautiful as they sound..

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.

Performance

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).
