Very True. I knew a person who worked at an exhaust shop. They sold two 
levels of muffler. One had a year warranty, and the other was a lifetime 
warranty. As it turns out, they were the exact same muffler. But when 
they installed a lifetime, they drilled a small hole to let the water out.

My 5kcstq had a little hole in the muffler. Though, it *was* a rust hole 
that just happened to let water out.
