G20/M340 Undercarriage Mid Brace Options - AWE Exhaust Rubbing

I'm tired of my AWE exhaust rubbing on the mid-brace. I've adjusted the exhaust several times, and eventually, it works its way to rubbing on the brace. Rather than take it off, I'd like to get an aftermarket one that dips down a bit. I'd like to find something like the G80 mid-brace for my G20. I had thought about using washers to space down the stock brace as well. Thoughts?

Have you tried getting into contact with AWE? I’d go the route of getting them to resolve the issue as it seems odd their set up would rub against the brace

A lot of guys have rubbing issues with the AWE exhaust even after taking their car to AWE and having it adjusted, or a pipe replaced. I've tried tightening the clap down more as I'm thinking the driver's side pipe rotates enough to cause rubbing.

My gf had the same exhaust installed on pre-lci and lci m340i. She did not have any issues with the pre-lci fitment, but with the lci we simply had the brace permanently removed as the shop said there was no way to get it not to hit.

We have been thinking of getting some washers to give it just a tad bit more space as the way we have the exhaust aligned now barely touches the brace.

I have a Pontiac G8 GT (and my M340i). With headers and 3” exhaust there’s rubbing on a similar cross brace. A lot of people take the brace off. The rest of us use washers and longer bolls. After 12 years, everything is still good. In other words, do washers and bolts with blue loc-tite.

Simple fix. Spend $4 at a local hardware store on thick washers. Remove brace, place washers between body and brace, and the install bolts. Problem solved.

What brace is that? Does it have big impact?

It's one for the G80 M3. I haven't seen one for the G20. I think I'm just going to get 2-3 washers for each bolt and call it a day.

That doesn't look nearly as good as the G80 brace I posted (although, not sure it matters considering it is simply a brace under the car that no one sees), and the price is a bit crazy. I'm still leaning on going the washer method at this point.
