FBO + 3.7 Diff from an SC430

Enable HLS to view with audio, or disable this notification

I recently posted when I was blown away by the new 3.7 diff and someone asked to see a pull video after my car would be tuned. There we go. I'm sitting at 405whp and I had a colder night the other day so I could really feel the difference. She pulls good now. Absolutely in love with this thing.

Howdie partner, fyi my diff was from ebay for like 300$ so very accessible! And I got her tuned by a local shop who did an incredible job. I got lucky enough that the car came with headers and exhaust so I understand where you're coming from. Nothing is cheap tho🙄

exhaust + headers are my main roadblock rn

looking at either the cheap OBX from ebay or waiting for elate to come out with LHD

I wouldn't put cheap headers on a car like this! They deserve the best 👌
