I did the spacer mod to the exhaust....

There are some suspension bushings nearby that may be susceptible to long-term damage and there is some wiring above and to the left of the left flange that looks like it could definitely be a problem. I did mine several days back, using only one washer, and can already notice some softening/smoothing of the corrugated tubing that encases the wiring. I'll be putting mine back to stock while my muffler guy and I try to figure out how to get more engine/exhaust noise into the cabin without waking the neighbors or breaking the bank.

If you want to keep the washers, adding some insulation to the wiring would probably work very well. Just about anything made for under-the-hood use should do the trick.
