My 04 has a set of Random Tech Cats. While my car was idoling I walked by and I thought I heard and exhaust leak. I looked with a mirror and found that I have two holes in my cats. One on each side where the support bar attaches to the pipe portion of the cat. It looks like the bar and weld just ripped off the pipe. The hole is about 1/4"x3/4". Has this happened to anyone else? Did you have it weld repaired? If I weld it I am afraid it will just happen again.
