This is the 323 pipe. I believe it is Nos as the baffle shows no signs of heat. Is it the #2 or #3 pipe? I believe it is #2. School me.

I have just begun to inventory and clean these up. And yes they all appear to be in nice clean condition. I will clean and inspect the 318s and post them up. Yes all are for sale.
