At Wolfpen in Roswell, Georgia, we have formed excellent relationships with many aftermarket companies selling intakes and exhausts for your German sports car. We’re an authorized APR and Dinan vendor, and we also source and install exhaust systems from Valvetronic, Dundon, and GMG among others. Because we’ve performed so many upgrades, we can also work with you to find the right exhaust note and capabilities for your intended use. Interested in making as much noise as possible? Want something with valves that can be open or closed? Need the lightest possible exhaust that can add real world horsepower? We’ve got a variety of options to suit your needs, and we’re happy to source a particular system that you have your heart set on. From giving an Audi turbo four cylinder a bit more bark to unleashing a Porsche 911 GT3 RS scream that will rattle your eyeballs, upgrading customers’ exhausts can be both thrilling and rewarding.
