What's up guys?? I'm Logan, I'm new here, don't really know how these forums work....
I have a 1980 Datsun 280zx Base model, and I was wondering if anyone here would happen to know what the length of the exhaust system is from the catalytic converter back to the muffler??? ALSO I need to know/figure out how many inches to cut out of the exhaust to make the exhaust system fit the car???

I bought a new exhaust system for it and they sold/sent me a 2 1/2" exhaust system which is made to fit 2+2 models ((has the back seat)) and I think he original exhaust pipe on a 1980 Datsun 280zx was 2" - 2 1/4"....

If anyone can answer my question or help me out with this, I would very much Greatly Appreciate it, Thanks
