BD 6.5L Down Pipes

3" Turbo Downpipe Kit
Application: 93-00 GM 6.5L Diesel
  • Product Warranty
    1-Year Parts & Labor
  • NOTE: This product CAN NOT ship to California due to CARB regulations.
On the original 6.5 engine installation, the turbo down pipe is attached and results in a crushed pipe. On the original 6.5 exhaust, there are flow restrictions at the turbo outlet pipe and in the muffler. The rest of the pipe is usually only a 2.75" diameter. BD's 3" and 4" full mandrel bent aluminized pipe corrects the problem, giving the engine what it needs; improved turbo response and high airflow ability.
BD aluminized pipes
Aluminized down pipes, cat-back and complete exhaust systems for earlier diesel trucks. Featuring large diameter, mandrel-bent tubing, BD’s aluminized systems are a great performance value.
NOTE: This product CAN NOT ship to California due to CARB regulations.
