Default Tunnel Brace Aftermarket Options?

Installed a 3” CarTreats midpipe yesterday. Long story short the OEM tunnel brace and middle support brace will not clear the midpipe. Are there any aftermarket options that clear cat back exhaust larger than 2.75”?

I’ve got the front brace covered. Can anyone speak to the F Sport support brace clearing larger midpipes?

This did not work. I installed four M8 washers on each of the four mounting bolts and the support beam did not mount up. Not enough clearance between the midpipe and beam with four washer stacked up.

The F sport brace should clear. But, it will tough to find one now. Here's a picture of mine which I just sold the other day.

Ran into this issue too but wasn't in a position to buy an aftermarket one. So I just spaced it with spacers and longer bolts. Works a treat and no vibrant. Maybe when my money tree starts sprouting...

I will be making another trip to the hardware isle today. I found a F Sport brace for sale but she’s seen better days. Lots of scraps and marks of being on a lowered 2is.
