now that you think its droning my pickup truck had a flowmaster at the end of the pipe and without a tail pipe I had what you are descrribing. It was very annoyng. Once I got the tail pipe on it got better but probably just because it was further away, (but it is still there). Which you cant do with the vette design...I've heard of flowmaster droning on this forum before...at leasst you are narrowing it down!!!
Not sure what equipment you have? Can you cut and weld? If you can it's essentially the cost of the materials for the cross-over. It might be well worth it to get the stock support brackets and modify the other end to hook up the mufflers...... or if you really hate yours, then get the stock mounted mufflers.
For budget purposes, if I was keeping the mufflers for now, then I would take a generic support bracket and modify it like the stock corvette mounting bracket so it mounts solidly. Then I could take my time to figure out the long term plan.

There's no muffler shops in your town? Any such place could put in a crossover.
Belgium. Not so easy here. On my last ride, it took me forever to find a shop willing to install a crossover... even with a kit supplied. And that was 10 years ago.

I wish I wish I could weld (and had the gear). Ooooone day
The current plan is stop gap. I suspect I’d really like a stock set up with a balancing tube.
The stock set up is too quiet, you'd probably get tired of that quickly as well...after all you do have a Corvette it should sound sort of mean.
It too bad that you can't get simple muffler work done over there, seems almost unreal. I have no experience with those inserts, but if they don't fix your problem, the Flowmaster Deltaflow 50 series mufflers do not drone at all, are quieter than the 40 series and would be a fairly easy fix....if you can find a shop to do it for you, I have these on my car.
Wow... that was fast. The exhaust inserts and hangers came in quite quickly. Good ol’ Summit Racing.
Reading the instructions on and in box, it seems that if you are just running pipes, the insert should be placed after the collector.
If you’re running muffs, you can put them in the tail pipes.
These inserts do not look very sophisticated.
The fit is super tight, I think mainly because my tailpipes are slightly ovalled-out. The instructions say to grind off a few thousandths, but there not very much meat on the discs.
I think another option would be to simply pound them in, understanding that they will never be coming back out.
I think I’m ok with that, because if this fails, I think the next step is to swap out my mufflers with known quieter ones.
There’s a small garage around the corner and the mechanic there says he can do it.
Let’s hope this solves the problem. I will also be asking him to go through the exhaust hangers to make sure things are squared away there too. He says he can handle that too.
