So I dropped my car a little bit lower than where it was cause I wanted to test my PBM's. Well now the dummy cat on my header is damn near on the ground and is destroying the concrete where my garage is.

Is there any way to grind down the bottom of this slightly? I can see where the piping comes out theof the dummy cat, so I figured i could grind it down a little withing risking an exhaust leak. Any other ideas? Would an aftermarket header give me more ground clearance? There is a decent sized car show this weekend and i dont wanna raise my car up but i just might have to.
