C2 Off-road Exhaust System Availability

[James W.]

Does GM still offer this system or do any aftermarket vendors make this system? I need to replace my exhaust on my 64. Can anyone comment on which vendor makes the best welded under-car exhasut system in either aluminized or stainless steel? I heard good things about Allen's. I want a system that fits and is as close to a GM NOS system as possible.

As far as I know, nobody makes reproduction N11 mufflers, and they were discontinued from the GM system many years ago. Paragon also can supply welded systems.

So none of the vendors makes a "correct" off road system? What is the part number on the muffler? I've got a set laying in the garage. Old GM. I curious now!

The mufflers have 3845735 (left) and 3845736 (right) debossed on the skin, with "GM" debossed directly above the part numbers; they also have "OFF ROAD" (1st line) and "ASSEMBLY" (2nd line) stenciled adjacent to the part numbers in white paint.
