I have one, I am thinking about switching from LM1 to LM2 mufflers to quite it down but might switch complete cat backs as well. Warning, this thing is LOUD. It wasn't so bad before the longtubes, and I was in my twenties. I have had the system on the car for 15 years or so but I have maybe put 8 or 9k miles on it. Car doesn't get driven often. I had the car on the lift yesterday and it still looks awesome. I don't know what it is worth. Make me an offer (I generally hate when people do that, I am not trying to auction it off). I just want to see if it is worth it.
