I ran a Restoration shop for 20 years and still do it on the side. Restoration 101- NEVER make assumptions. Just because this is a "new restoration" a red flag went up immediately with your comment "and it is a new exhaust...I THINK". You need to check it.
Dealing with aftermarket parts I have had DOZENS of odd failures and issues from NEW parts that took weeks to track down. All due to poor manufacturing quality. One of the internal baffles in the exhaust may have slipped into the incorrect position or was welded in improperly. Also...I have seen on several occasions restored vintage cars that have been stored over winters that have the exhaust filled debris by hibernating rodents. Even nice buildings have mice....
But it is your car and do with this info as you please, but discounting it without finding the cause is not a good idea. Keep the info in back of your mind and when you run out of other ideas check into it. It could very possibly be the cause. That is a CLASSIC plugged exhaust symptoms you have.
