The NEUSPEED Hi-Flo TDI Turbo Discharge Pipe removes the damper chamber from the discharge side of the turbocharger. First, a newly machined billet aluminum mounting flange with a smooth bore mandrel bent full size tubing from turbo outlet to rubber hose. Secondly, the internal machined groove on the mounting flange uses the factory "O"ring to ensure leak free performance. All restrictions are removed with full diameter flow and with no modifications to the vehicle - this is a bolt-on part. You can expect better response, more horsepower and torque.
