GTHaus
GTHaus offers Audi R8 and Mercedes-AMG exhaust upgrades, including cat-back systems and downpipes with high-flow sport cats, suited for daily driving and track days.
VAG Motorsport carries GTHaus products for Audi, BMW, Ferrari, Lamborghini, and Mercedes-Benz. These parts focus on performance exhaust flow, sound control, and fitment-specific hardware for modern street and track builds. The range includes systems and options designed around material choices like stainless steel or titanium, with configurations that support both quieter cruising and higher-output use.
Common categories include cat-back exhaust systems, axle-back/rear muffler sections, mid-pipes and X-pipes, downpipes with high-flow sport catalytic converters, and straight-pipe sections that replace secondary catalysts. Many applications also include electronically controlled valve hardware, plus related upgrades like wireless valve remotes. Product pages are typically organized by a selection guide for make, model, and submodel.
Available through VAG Motorsport, GTHaus exhaust options are built around specific chassis and engine fitments, making them suitable for daily driving and track days. Depending on the application, you’ll find valved configurations for managing cabin volume as well as freer-flowing sections for performance street use. Supported vehicles include Audi R8, BMW M models, Mercedes-AMG platforms, and supercar applications like Ferrari and Lamborghini.
