OP, I am sorry if you have taken my comment as a troll. Of course everyone can do whatever they want with their car, and everybody knows the Z could and should sound better stock, without having to spend $$$+ for an exhaust product.
Having said that, I was just expressing in a funny way my idea that, always in my humble opinion, the washer mod is a cheap mod that doesn't really do justice to a +$40k car. It's a forum opened to car lovers and I believe you have to deal with both people that compliments you and people that don't. My 2 cents
