CTS Turbo B7 Audi A4 2.0T Test Pipe

CTS Turbo's test pipe for the B7 Audi A4 2.0T removes the factory catalytic converter to provide unrestricted exhaust gas flow from the turbocharger. Engineered specifically for 2005-2008 B7 A4 models, this test pipe reduces backpressure and heat buildup in the exhaust system. The direct-fit design replaces the restrictive OEM cat with a smooth-bore pipe, improving turbo spool characteristics and throttle response. Constructed from durable stainless steel with precision flanges for secure, leak-free installation. Intended for dedicated track vehicles or off-road use where emissions compliance is not required.
