66 corvette N11 off road mufflers part# 3845735 and #3845736

[Matthew L.]

Was just going over our newly purchased 66 427 car and noticed the mufflers have gm and #3845735 and #3845736 embossed in the muffers. Could these be original N11 offroad exhaust mufflers?? Does the reproduction N11 mufflers have these designations on them? The mufflers dont appear to be new by any means but are nice.

I believe you will find these are GM over-counter N-11's commonly seen now days. The assembly line N-11's had some embossing but no part number and were stamped with yellow ink that said off road assy. There is a lot in the TDB archieves on these if you want to search. Picture of original N11 on a well known 67 Bowtie car.
