Re: 67 Off road exhaust

65 to 67 off road exhaust N11 is same for Big block or small block. Part numbers 3845735, 3845736
There was a newer GM over the counter replacement back in the late 80's or 90's with embossed part number 3845737 It replaced part number 3845735
Hope this helps. Grant

There was never an actual part number change for the 3845735. In fact, it was available under that number right up until the time it was discontinued without supercession just a few years ago. It may be that the number 3845737 did appear embossed on some of these mufflers, but it was never the finished part number for the N-11 off-road muffler/pipe assembly.

The right side pipe, GM #3845736, was discontinued without supercession in July, 1998.

The part numbers were the same for all 65-67 off-road muffler/pipe assemblies. However, all N-11 assemblies were 2-1/2" ; there were no 2" N-11 systems.
