USP Motorsports is proud to bring you our hand made in-house, tubular exhaust manifold for the 24v VR6 turbo converted Audi B5. We designed this manifold to be the perfect combination of quick spooling responsive power, and maximum top end horsepower. After real world testing on our shop drag car of a long runner tubular manifold and log style manifold, we have found this to be the best possible choice. Dyno proven to make 50+awhp over our previous log style manifold, with even quicker spool up time! This manifold was engineered for shop drag car to break horsepower and quarter mile records, not just to show nicely in the engine bay.
Note: This manifold was designed to run the turbocharger without an air filter. It is intended to use a headlight cutout as a ram air induction system. A screen can be used on the turbocharger for any necessary street driving.
