Dual exhaust conversion

I have a 90 D150 with 5.2 engine. Wanting to install dual exhaust but keep the factory 02 sensor/computer system. Has anyone had success with doing this. Thanks, newtjr

Yes, just have the drivers side header 'bunged' for the O2 sensor.
I did this on my '90 D250. I used stainless steel block hugger headers.

Did you have any driveability issues or do any computer changes/mods. Thanks

As long as you keep the O2 sensor, it will be fine.
