A company that treats its customers this way can take their business elsewhere. I was very close to ordering the Eisenmann Quad Exhaust, but I didn't get any replies to my multiple PMs and emails to Eisenmann.
This company doesn't seem sincere about helping it's consumers. Insulting one of our forums most skilled and respected members places them on the bottom of my list. I'll wait for a more reputable consumer-related alternative.
