Installed high flow cats and wow, it's too loud
I've got the SOLO Axle-back without mufflers, a true X-pipe and now I installed high-flow cats today and it's the most obnoxious raspy loud and I kind of like it! I think I need some mufflers now though.

If it's too loud, you are too old....

A resonated X might help. I have ported stock manifolds, SOLO HFCs, and SOLO catback, which only has a resonated X and my car is not raspy or overly loud. I did add J pipes to kill hiway cruising drone though.

The Solo high flow cats are a great upgrade but without mufflers you'll get some rasp for sure. Try adding a Solo Mach-X mid muffler in place of your X-pipe. Then you would have pretty much built one of their Mach-XL catbacks.

I'm running the HFC's, xpipe no mufflers/resonators. Rasp isn't too bad although it is there however it's not a big deal to me.

This is some good advice. I have Long tubes, high flow cats, and the Mach-XL and it is not too loud even with the top down.
