BD 3" 2 Bolt Flange Downpipe Kit fits 1993 - 1994 Chevy GMC 6.5L without catalytic converter.
Part # 1046545.
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.
